Offset value = 1/2 thickness of component . Then show 2D detailed to check Thickness . How to write a tool tcl to perform that operation ?
  3. Hi , Is there a way to edit panels created using *createmarkpanel? we get a panel by using the command " *createmarkpanel nodes 1". We have only proceed option in that panel. Is there any way i can edit the panel and create 2 buttons called "Reject" and "Return" Thanks, Bharath
  4. 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
  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 facing a problem while creating a 2D surface mesh in TCL Code in hypermesh. The settings done in "*interactiveremeshsurf" and "set_meshfaceparams" seem to be ignored for all surfaces and overwritten by the settings written the GUI at 2D-->Automesh-->Edge deviation. The code can be seen below: *setedgedensitylinkwithaspectratio -1 *elementorder 2 *startnotehistorystate {Automesh surfaces} *createmark surfaces 1 [lindex $List_OP($i) 0] for { set ii 1} {$ii <=[llength $List_OP($i)-1]} { incr ii} { *appendmark surfaces 1 [lindex $List_OP($i) $ii] } if { 1<=$i && $i<=3 } { # markmask, elementsize, elem_type (0 trias, 3 rtrias) *interactiveremeshsurf 1 0.25 3 3 2 1 0 set i_am 0 foreach Element $List_OP($i) { # index (von 0), elem_type, alg_type, elem_size *set_meshfaceparams $i_am 2 3 3 0 1 0.5 1 0 *automesh $i_am 1 3 incr i_am } *storemeshtodatabase 1 *ameshclearsurface *clearmark surfs 1; *endnotehistorystate {Automesh surfaces} Am I missing some command? Thanks and best regards, Henrik
  7. I am trying to squeeze a femur model with two sets of stiff springs top and bottom, and allow it to rotate with the other (spring BCs come from a research paper). Instead, the model bends where the mesh meets the springs that should remain mostly straight. However, I have tried adjusting all DOF stiffnesses in the PBUSH card without luck. All springs have been assigned to the local coordinate system (shown in right on photos) using CBUSH card. It seems to me I need to stiffen K2 or K6 (y-tension, z-moment), but neither of these solves the issue. Attached graphs show "TY" stresses. Femur_Model_6_26.fem
  8. how to subtract two tetramesh components from one another in hypermesh? I was having stl files, then I have converted them into 3D tetramesh. Now i want to subtract volume of one part from other.
  9. Hi, I need SCRIPT for automatically saving Hypermesh with an intravel of time. Please help anyone. Thanks in advance. Thanks, Dinesh chellaiya
  10. Hi! I'm trying to mesh a solid with TetraMesh and it states the following error: "2 edges failed nodal setup. Meshing failed". But I can't see anything wrong or red colored or anything that tells me where the mistake is. Even with visualisation options. The solid is created properly with bounding surfaces so I guess there are not free edges. Could you help me?
  11. I have a mesh in component1 and another mesh in component2. Is there a way to do a node equivalencing operation from comp1 to comp2? What I mean is, while I do this operation, I don't want the nodes on comp1 to equivalence to nodes on comp1 (no node equivalencing on the same component) Thanks!
  12. Hi, I have a model with multiple components that shares several materials/properties. I want to know the number of elements associated to each material/property within each component. For example, one component is made of 100 elements which are assigned to 22 different materials. I want to know how many elements within Mat1, Mat2, Mat3, etc. Right now I am doing this manually by isolating each material and counting displayed elements. But this takes long time and very tedious. Is it possible to automate this task by writing a TCL script or exporting a custom output file? It would be very nice if I can get something like: Mat1 Mat2 Mat3 Mat4 Matx Component1 10 9 50 0 XX Component1 15 55 4 22 YY Thanks, Mselim
  13. Hi everyone, I am modeling a 3D hollow element made by more components in Hypermesh to conduct NLQS analysis with Optistruct. My system is symmetric and I want to know if there is the possibility to tell the software that the unmodeled part is the mirror of the modeled part, so that it considers the constraints due to the symmetry. I know the software allows to reflects elements, but I would like to not works with too many nodes. I attach pictures: 1 is the modeled/discretized part; 2 is the entire system (modeled, unmodeled parts) Thanks Martina
  14. Hello everyone I have a quite complexe geometry to mesh. For this I have applied 'Check Elements Quality Index', where it shows the quality of the elements. Now I would like to know, if there is a possibility to cut the model, to be able to see the inner contours and how the elements looks there. Then I could have a better overview of the situation and know what to change for the mesh. I thank you in advance for your help!
  15. 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.
  16. 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!
  17. 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
  18. 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!
  19. I wanted to apply a load on a surface for which I want to calculate the surface area so that I can apply a pressure load on the surface instead of concentrated load ? Is pressure load applied is evenly distributed on the on surface or it is mesh or node dependent?
  20. how to find nearest node in hypermesh. A command or any macro that should search a tolerance of distance like within radius of 30 and then find nodes within that perimeter . lets say, should find nodes adjacent to it.
  21. Dear Community, I would like to present you a possible bug I found in Hypermesh 2017 when it creates the input file for optistruct including a buckling analysis (due to limited time, I have not checked if the same problem appears with other analyses). Please find attached an example and refer to the example for the description below. When you try to create the Optistruct file to run (for analysis only, -optskip), Hypermesh creates the following subcase card for buckling: SUBCASE12345678 LABEL Linear Buckling ANALYSIS BUCK SPC = 1 METHOD(STRUCTURE) = 3 STATSUB(BUCKLING) = 1 The first row is missing a space and the solver gives you the following error if the space is not added manually: *** ERROR # 1461 *** in the input data: Card "LOAD" is not allowed for this subcase type. The problem seems to be present only if the loadstep ID is made by 8 digits. I hope this will be helpful to somebody. Regards, Alessandro buckling_issue.hm
  22. Hello, I'm working with linear dynamics (modal, harmonic and transient) analysis in OptiStruct and I wonder if I can extract the results of displacement, velocity and acceleration in list format or export to excel?
  23. Hello, I am using VWT to access to the surface pressures on a model. These are then to be exported and applied to the model within HyperMesh via linear interpolation. I recently came to realise that if I move the model in VWT then the nodal pressure coordinates that I can then export to a .txt file are wrong. They do not align with the nodal coordinates of the model within HyperMesh, but refer to the region of space that they occupy in VWT. Thus, you must translate and rotate the model in HyperMesh first. This is justifiable and works for just one loading scenario. The problem I am having is that I wish to do a weighted compliance topology optimisation with multiple loading scenarios that require the angle of incidence of the flow to change. Therefore, if I rotate the model, the pressure files nodal coordinates will change and I will not be able to use the same hypermesh file (as it will have to be rotated accordingly too). So, is there a way to change the direction of the flow or rotate the windtunnel within VWT - so that my model can stay constrained in its geometrical space but the loading scenario can change? Thank you in advance.
  24. Hello all, in the analysis of cold plate . I have fins inside the fluid domain and outside the cold plate. If inside and outside fins are treated as thermal shells in acusolve then in hypermesh the elements of fins will be in which collector: fluid collector or coldplate solid collector? As in pic you can see the placement of inside fins and outside fins. Please help.
  25. Hello, I have a query regarding the algorithms followed to form 2d surface mesh. In the help file it is mentioned as advancing front algorithm and sub mapping algorithm, but how these work is not explained . Can anyone share or describe the process.
