  1. Hi all I would like to get a list of thickness for selected elements. I wrote these codes but it gives just one thickness as a result. Could you please help me ? *createmark elements 1 179 79 150 279 35 ... set test [hm_getthickness elements 1] foreach elements $test { puts "$test" }
  2. Hello, I would like to have a node numbering in a prescribed order. Requirement - Nodenumber sequence from top to bottom and follwing the same from left to right in the X-Y plane. This works well as shown in the figure. The requirement is to witness the same numbering order in all the X-Y planes along Z axis. The drag option along Z axis is used to create 3D elements. I dont achieve the node numbering in the same order as that on the 2d plane. The node numbers skip and have no sequential order as shown in the figure below. The renumber option available did not turn out to be of much help. Any sorts of suggestions or help is appreciated. Thanks, Sankalp
  3. Is it possible to create some commands or steps to follow so that when somebody else opens the file he/she can read them and know how she/he has to hide or show assemblies for a certain type of analysis or load steps? I hope I explained well. Thanks in advance!
  4. Hello, Is there a direct process for dragging the selected nodes for creating the elements and maintaining their connectivity with nodes along the red line? ( I am asking about a direct process in which I will not require to split / edit the surface or change the number of nodes on an edge) Thanks Bharat
  5. Hi, I need to add a customized button in the panel below. Kindly help me find the solution Regards Saumya Mishra
  6. Hello, I am a civil engineering student who is using HyperMesh to create a model of a small-scale tower as part of a civil engineering design club. I have no prior experience with HyperMesh in the past and am currently learning all of its functionalities and capabilities on the spot. I am currently having a problem with creating a uniform "hex8" solid mesh for the solid in the image below: The mesh, containing 3-D quad elements, has been created, but there are warped mesh elements along the sides of the component: I would like to be able to make all the 3-D mesh elements cubes, all with side lengths of 0.0127 units, and these mesh elements will correspond to only one component. If anyone can offer tips on how to resolve this, that would be much appreciated! Thank you very much for your help!
  7. Hello, I'm a beginner user of HyperMesh and OptiStruct and I have to create a 3D mesh of a solid CAD (1 component) to perform a linear static analysis and to do a lattice topological optimization later on. After the import of the .step component, I tried to mesh it with the Quick TetraMesh tool but it generates a "meshed component" different from the first one, as well as a new material. How can I make the 3D mesh directly on my component (as I can do through "Volume tetra" tool by the onglet "Elems to Surf/Solid Comp")? Or, how can I manage the meshed component and the new material created in order to complete the analysis? Thank you in advance,
  8. Hello, I am using HyperMesh 13.0, and I want to automesh a large number (hundreds) of CAD files containing only 2D surfaces which have minimal geometry deviations such as varying in fillet radii. It is parametric CAD models with fillets as varying parameters. BatchMesher works well for me in generating a 2D surface mesh and the mesh quality it generates generally is acceptable for my purpose. However I want to fix a number of elements in the fillets in my CAD models, and I can't find this option in the BatchMesher parameters. At the moment, some models with smaller fillet radii have insufficient number of elements. I have read the help manual, and it says there is a way to specify the number of elements along the fillet, which is what I want, by modifying the Parameters file. However when I add a number to the "minimum number of rows" box, it does not work. Image is attached here from the help section. Please can someone tell me know how to fix the number of elements along a fillets when using BatchMesher? Many thanks, Hamid
  9. Hi there! I am trying to simulate a flow of humid air running through an helical pipe. As the air flows, it gets cooled from a negative heat flux on the walls of the pipe. Any thoughts on how can I approach this problem? Currently, I am not able to run the simulation because I get an error "Negative absolute pressure for humid air".
  10. Hi, I have a question regarding the Turbulence Intensity parameter that is located under the solver browser in Hypermesh 2019.1 (AcuSolve User Profile). What are the units of this parameter? Is it represented as a percentage or ratio? (I've attached a screen snippet) For example in AcuConsole GUI, the turbulence intensity parameter is input as a percentage (e.g 2.5 for 2.5% turbulence intensity). Best regards Brenton
  11. Here is my .hm file. I would to connect the design and non design component as a whole but i still do not manage to do it. Please help me guysss !!!! TRY.hm
  12. Dear everyone! I want to export my ply-based shell composite laminate from HyperMesh to a STEP or PARASOLID file. I used the following option: File>Export>Geometry Model My composite laminate can not be imported properly into Solidworks 2019. Tried a lot of options but I could not reach that the shell elements (and plies) had the proper thickness. In Solidworks there was only a surface without thickness. I would like to design a tool for manufacturing and I need the proper geometry of my composite part. Thanks for your answer in advance! Imre
  13. Is there any way to display the reference geometry in HyperWorks 2019.1 X? In HyperCrash there is an option to display it. But in HyperWorks X I cannot find the way to show the reference geometry, even the "Preview" option does not make it. See the same opened file side by side.
  14. Hi everyone, is it possible to define as input data the behaviour curve of a non linear elasto-plastic matierial in a MAT1 card image material with the NL parameters activated? I tried to import the curve, changing the TYPSTRN value, but the solver Optistruct does not start. The curve has non linear trend both in the elastic that in the plastic phase. Bests Martina
  15. Hi everyone, I wonder whether it's possible to configurate as a shortcut the 2D--> quality index. I know that from Preferences>keyboard settings I can change shortcuts, but i need the scripts and I can't find that one in my folders. I use Hypermesh 2019.1, many thanks! Regards
  16. Hi there, I would like to know if there are easier ways to select multiple edges. For context, my model has many profile lines and I would like to select and suppress them for a better mesh quality. Something ideal would be to be able to select these lines in a cursor-drawn rectangle. Please let me know if a shortcut or any easier way is possible to make pre-processing easier. Regards, Jess
  17. Hi everyone, I am simulating a tensile test of a homogeneous isotropic material, according to the coupon bar example in "Introduction of Non Linear Finite Element Analysis using Optistruct". I imported a different material and the coupon bar geometry is a bit different. I do not understand why the numerical force -displacement curve decreases after the yielding point, while, for example in the ebook, it follows the input trend. I though the possible problems could be the definition of the true stress-strain curve, or the NLQS parameters NINC and NLOUT, the chosen finite elements (tetrahedral; I used this type because I have to calibrate the material to perform analyses on more complex geometries). Can anyone find the problem? I attach the .fem file (ModelB_prova_NLQS). In additiion I attach a model that behaves as expected (Model2_surf_prova10_NLQS ModelB_prova_NLQS.fem MODEL2_surfs_prova10_NLQS.fem
  18. Hi everyone, I need to define a surface from a set of lines that represent level curves of a set of mountains. The creation of surfaces from lines does not work well. Is there a way to obtain good surfaces? Bests Martina
  19. Hi everyone, i would like to know if there is any tcl that extracts the midline of all displayed thickened pipes comps. If not, is there way we can create a tcl to extract midline for all the displayed hollow thickened pipes.. Thank you in advance
  20. Hello, i am trying to calculate von Mises stress for a beam. The beam has a weird cross section and i already defined the section in hyperbeam. for properties i use PBEAM, since there is no cross section that is the same in optisctruct library. i have gave the value for continuation line 2, 5 and 6. in Output, i have requested stress for all type. There is no problem during the calculation and in the result type(Hyperview), it only shows Displacement, Element strain(1D) and Element stress(1D). Under Stress, i can only choose axial and long. stress, but i need von Mises Stress. How can i obtain the von MIses stress? thanks in advance
  21. Good morning! I'm trying to model the 4 cables shown in the attached file. At first I thought of using Beams to make it easier but the fact is that those cables cannot transmit moment (rotation) in the joints (2 joints in each cable). How should I do it? Do I change the element type? Is there any way of erasing restriction of the rotational DOF at the joints? Hoping a quick response and thanks in advance! Conjunto tubos.STEP
  22. Hello all, In a part of my script the vector coordinates are pulled for a later use. When I execute I have the following error message --------------------------------------------------------------------------------------- Error: can't read "vx1": no such variable while executing "*createvector 1 $vx1 $vy1 $vz1" --------------------------------------------------------------------------------------- Code: *vectorcreate_twonode $x $y set vectorList [ hm_getmark vectors 1 ]; foreach vct $vectorList { set vx1 [ hm_getentityvalue vectors $vct "xcomp" 0 ] set vy1 [ hm_getentityvalue vectors $vct "ycomp" 0 ] set vz1 [ hm_getentityvalue vectors $vct "zcomp" 0 ] return "{ $vx1 } { $vy1 } { $vz1 }" } *createmark nodes 1 $x *duplicatemark nodes 1 25 set r [hm_entitymaxid nodes 1] *createvector 1 $vx1 $vy1 $vz1 *translatemark nodes 1 1 10 ------------------------------------------------------------------------------------------------------------- Would be great if someone could tell how to reference the coordinates vx1, vy1 and vz1 in the other parts of the code. Thanks in advance
  23. Good afternoon, I'm trying to mesh a housing and I wanna model parts of it with SHELLS and others with SOLIDS. How do I connect both? Thanks!
  24. Hi,I am trying to simulate a bird impact on a plate with RADIOSS. So I am creating my model on hypermesh now, i chose to consider the bird as a fluid with a density of 438 kg/m3. I would like to work with SI units and the dimensions of the bird are : 0.1325m long cylinder with two hemisphere ends having a radius of 0.075m. I am now trying to mesh this geometry with the SPH module in hypermesh. So i entered a pitch of 1e-3m and a density of 438kg/m3 as i said before. But when i create the mesh, nothing happen and i only get this message "0 mass elements created". I attached my file with the topic. I don't know what could be my error, more of that I tried to do it using mm instead of m and it worked... But I really want to use SI units. Thank you in advance for your help, Gaspard.
