  2. Hi all, After topography optimization, how can we get the optimized geometry by using hypermesh? How to use OSSmooth panel? Roy
  3. Hello everyone, I think this is a basic question, but I am unable to get it working. I am using Hyperworks 14. I have a block of solid hexagonal mesh and I am trying to add new components by selecting a subset of the elements. I am trying to work with the 'organize' panel option, but I had no success so far. To test it, I created a huge cube filled with hexahedral elements and a small rectangular surface within the cube. I was able to associate few of the nodes by doing 'Geometry ----- node edit ----- associate' and selecting the rectangular surface and small tolerance level. It shows that I have some of the nodes associated to the surface component. Now to select a subset of elements within the cube, I did 'tool ---- organize ----- collector ----- elements ------- by geometry ------ by surface.' It doesnt show any elements associated to this surface even though I have a few nodes associated to it. Could you please help me figure this issue? I checked other questions in the forum, but they dont help because I have a complex geometry to select elements for. Here is a small screenshot of what I am doing. I am following the directions from the help documentation below ('by geoms'): Thank you for all your attention, Bharath
  4. Hello, I encountered the following problem: after creating a 2D surface mesh on all surfaces of a solid I used tetramesh. Afterwards I reorganized the meshes so that the tetramesh belonged to the component of the original geometry and the 2D mesh was deleted. When trying to apply a line load onto the new tetramesh the following error occured: Lines are not attached to edge elements. I also tried to select the nodes by geometry and selected the desired line but my selection of nodes was not accepted. On the previous 2D mesh the line load worked fine. Do I have to actively attach the new tetramesh to the geometry or do so while creating the tetramesh? Or am I doing anything wrong when creating the tetramesh, so that the lines for line load wouldn't be accepted? Thanks in advance
  5. I am trying to create a j-integral domain for abaqus using hypermesh. I am having issues of circles not being imported with enough line segments, resulting in triangles and straight lines for these circles. I have included an image of the import. Any help would be appreciated. Thank you, -Clay
  6. Hello, is there any possibility to define a contact (line or Point) between two volumes? Or is a little distance between two independent volumes necessary? Thank you.
  7. In order to define a plane containing a circle, I need the center of the circle and the normal of the plane. Getting the center is simple using hm_getbestcirclecenter. I have not been able to find a means of getting the normal. If it were possible to get the coordinates of two points on the circle, I could use those with the coordinates of the circle center to calculate the normal. However, I haven't been able to find a means of getting those two points.
  8. Hi all, I am very new to using Optistruct and I'm having a weird issue. I run my model and the output file gives me zero errors. When I open the results some of the geometry from my model is missing. Specifically, it's the part of the geometry where the load is applied. Does anyone know why this happens and how to get the geometry to appear in the results? thank you!
  9. Hi I am trying to clean up the geometry of a particular solid. When I import the model from solid works to ABAQUS i get an error showing imprecise geometry and hence I'm unable to mesh it. I am therefore trying to clean up the geometry in hypermesh but im unable to detect any imprecise geometry as all edges show green. Can someone tell me how I should proceed in identifying and correcting the geometry Thanks
  10. Hello to everyone. A) First of all I would like to know if it's possible to update in SimLab a Creo CAD model (after being modyfied) which has been already opened and meshed in SimLab, by keeping connected the mesh controls setted previously. I'm gonna be clearer: 1- I import a Creo CAD model file (i.e. file name is PIPPO.prt) in SimLab as a part (.prt) or assembly (.asm) by using the command "Import->CAD" 2- I set mesh controls on the model and eventually mesh the component(s) (i.e. I set face mesh control on a face which includes a hole, and a washer mesh control around the hole itself) 3-In the meantime I modify in Creo the CAD model itself (i.e. I change the hole radius) then save by using the same name and overwriting the file (i.e. PIPPO.prt), which is still opened in Sim Lab 4- I import CAD model again (i.e PIPPO.prt) as done in point 1 => now I wish that model geometry could update automatically and that SimLab could recognize connections between the "new" geometry and the old mesh controls, unless big changes (i.e. face mesh control should be still active and linked to the modifyed face, while washer mesh control probably is now missing). Is it possible to do in SimLab? I read in the GUI that you should set the new quotes, when you modify the model in Creo (point 3), as design parameters, so that when you re-import it in SimLab you have to check that "Design Parameters" import option is on and model should update automatically, but I couldn't try this way cause I have another problem: B ) Everytime I choose the option "Import CAD" and I select a .prt or .asm file then Windows says that there is a problem in finding the installation directory (I am not the first person in my company who encounters the same problem, so probably is not due to installation errors). So the only option I have is to use "Import->CAD through traslation" that opens a step (.stp) file auto generated by SimLab, but all of that makes parameters being lost. Did somebody else encountered the same problem? Coming back to A) , and saying that the "design parameters" way could work, does it exist another way which can be even more automatic and simpler? Softwares Assistance once told us to try to assign different colors to different features on the CAD model in Creo to allow SimLab recognize the model during the re-importation. Did somebody ever tried this? Thank you very much for the support
  11. Hi, I've modeled a geometry on HyperMesh and i've exported it as a Parasolied (.x_t file) and now i want to import the geometry on AcuSolve in order to run a CFD analysis. And the import of the geometry on AcuSolve doesn't systematically work, and I don't knwo why. The problem is that i don't manage to find the reason why it doesn't work systematically. I've tried also .nas and .cas files, and it doesn't wor at all. I got this type of error : Could you please tell me steps to export the good type of file that can be read with AcuSolve. It would be really nice!! Or just tell me the reason why i can't manage to import any files on AcuSolve. Yours, Emmanuelle
  12. I am a student and I am trying to run an impact analysis of a truck chasis. There are more than 100 components and I have created mid surface of all the components to do 2D mesh. I facing a problem where there are gaps. I have tried to use the extend surface option but not abler to remove the gaps. Please help me out. have attached a pic for reference.
  13. Hi folks, I need to create holes in my shell geometry in hypermesh. It is possible? thanks
  14. We all know that hyperwork is unitless. But then i face an inconsistency in importing my geometry into hypermesh. I import same geometry, one in the form of Nx part file, another one is in parasolid, both with exactly same geometry. The geometry of part file after imported into hypermesh will have exact the same size as in Nx( let say the length is 100mm in Nx, the length after imported into hypermesh is 100). But if i import the parasolid geometry with length of 100mm into hypermesh, the length would appear as 0.1 instead of 100. How can i solve this inconsistency? It is important for me to standarise everything without using the scaling factor as i need to automate my process. I would use both Simlab and Batchmesher in my process, the inconsistency is a very big problem.
  15. Hi I have two objects and object A locates inside of object B. The outer object B is already meshed and saved as hm file. Object A is imported from IGES file. So I open B.hm file and import A.igs . I used boolean operation; {A-B,B}(cut A with B ). After boolean, I tried to mesh object A, but I cannot mesh it and the mesh is just attached to the inner surface of B. I would like to have hex mesh for B and tet mesh for A. Anyone can help me with meshing object A? I would appreciate any help. Thanks, Jay
  16. Any simulation carried out using AFDEX will consist of 5 different files, a simulation addressing file, two input files, and two output files. Files for addressing a simulation: The SimuLation addressing File(.SLF) contains information about the data files needed for carrying out an analysis. Format: .a2dslf and .a3dslf for a 2d and 3d simulation respectively Example: example1.a2dslf Input Files: The Simulation Control File (.SCF) contains the information needed for simulation control and is subject to change during execution. Format: .a2dscf and .a3dscf for a 2d and 3d simulation respectively Example: example1.a2dscf The Simulation Input File (.SIF) is about the workpiece, die geometry and relevant process information like friction, die velocity etc. In most cases, the user will be not be required to edit anything in this file as all the requirements will be satisfied in the GUI. Format: .a2dsif and .a3dsif for a 2d and 3d simulation respectively Example: example1.a2dsif Output Files: The Simulation Result File (.SRF) saves the input data, FE Solutions, and the process conditions. This file cannot be read by the user directly and can be accessed through the post-processor. Format: .a2dsrf and .a3dsrf for a 2d and 3d simulation respectively Example: example1.a2dsrf The Simulation Print File (.SPF) records the simulation history or the total procedure. The error information is also recorded. Format: .a2dspf and .a3dspf for a 2d and 3d simulation respectively Example: example1.a2dspf Note that a .PRJ file is generated by the preprocessor and functionally it is similar to the SLF. Working on the feedback from users over the time, AFDEX GUI has and is being improved continually to minimize the user intervention as much as possible and make the simulation procedure simple. The file types discussed above will come into play only when advanced forging processes are simulated. For the majority of applications, the user can simulate directly using the GUI. Let us know what you think and feel free to ask questions if you have any. Cheers from AFDEX Support Team!
  17. Hey guys, maybe I am unaware of a setting which causes this, but at least to me, this is strange. I have a modified version of the CClip Tutorial and when I mesh it, the geometry changes and neither the geometry nor the mesh has a node where it should be. .gif and .hm attached. Thanks in advance, Merula meshChangesGeom.hm
  18. Hello, I have a large model which has been cut and made mappable using Ansys. We have given names to each and every component in Ansys. When we are trying to import it in HM as a geometry, only few components are displaying their names. Can anyone tell me how to overcome this problem? What file should I export/ Import. thanks and regards, Bharat
  19. Hi all, I am writing a script to detect fillets in a geometry and defeature it. Right now i am using *separate_fillets command for fillet separation based on the given radius ranges (0-2, 2-4, 4-8, ....). But it is not giving a proper output. Some surfaces are missing in between and when i try to defeature, surfaces are getting destroyed. Is there any other command to detect/defeature fillets properly based on the given radius?
  20. Hi all Imagine you have a cyclinder in shell and the two end edges are red, since they are connected to only one edge, they can not be resolved changing the tolerance .mostly the toggling works when there's gap between two edges of two adjacent surfaces. what is the strategy for these two surfaces?
  21. Hi all There is a feature in Abaqus that you can choose a plane or surface on a solid that you can partition the solid by extending it. Is there a same option in Hypermesh and if so, what are the steps, and what are the preconditions that the feature would work in Hypermesh?
  22. Hi guys, I need to export .stl geometry file from hypermesh for a new drawing in catia v5. The stl file was generated from a topology optimization. Thanks
  23. Hi all, I'm performing a dynamic simulation using RADIOSS solver. I'm creating this kind of model : I used a COMPSH material law and an SH_ORTH property in order to model an "equivalent material", with a 4 mm thickness. When I run the analysis, I've issues regarding penetrations in my model. Nevertheless, when I want to fix them using the Penetration Check tool, elems are totaly deformed. Could you please help me with this model ? Best regards, Raphael
  24. Hello everyone, I tried to figure out what kind of geometry is shown in a model I received recently. When I delete or hide all solids and surfaces, that's what's left in the end (picture below). Any idea what kind of geometry it might be? I tried to delete all kinds of geometries or elements using the "Delete" tool > All for all options in the Dropdown list shown below. But the points won't vanish. Maybe I'm missing something here... Kind regards, Niclas
