  1. Hello, I am quite beginner in Hyperworks and I am currently modelling a laminate (HC panel) with different plies. Whenever I make a modification in the mesh, before running the calculation I need to re-open Ply card and specify elements that are included in each ply, because they are lost due to mesh (thus, element) modification. I am wondering if there is another way to specify plies, because it might be relatively annoying to update this part of the model each time a mesh modification is carried out; in this case, number of plies is not extrenely big, but it can happen that a model consists of many of them, leading to a high waste of time. For example, that instead of selecting elements which would be involved in a ply, surfaces could be selected. Any help would be helpful. Thanks in advance. Regards
  2. Hello, I'm using HyperWorks 13.0 Student Edition and suddenly a hm file started to take minutes to open or to edit anything (specially surfaces). When I try to mesh something the program enter the mode "Not responding". What is that? What should I do? I've already tried to save as another file, to import then save, to restart my computer, to clean my temporary files, etc... But i think that the model has some problem. Thank you.
  3. Hi Everyone, I'm new to Hyperworks and working my way through the tutorials but for some reason I can't seem to see meshes on my parts when I create them. Here's a screenshot of what I can see: No matter how far I zoom in the mesh doesn't appear, and I can only see it when using the "shrink" visualization setting, which appears as below: My graphics card driver should be up to date as I just updated it a few weeks ago. I'm running a Radeon graphics card on Gentoo Linux, and using Hyperworks 14.0 Desktop. Thanks!
  4. Hey Guy, hope you can help me I got a quick question about meshing a volume. Think about a cube with equal face sizes. Now I want to mesh this thing with a "Quads only" mesh. Important is that the mesh becomes finer and finer to the middle point of the volume. Is there any easy way without Splitting up the cube? I already tried to split up the cube and use the bias function on the edge of every quater of the cube. Unfortunately the results of my Simulation were quite bad. PS: I'm simulating some electromagnetic Problems an I want good results near the coil in the middle. Thank you guys!
  5. Hi, I am trying to create a boundary layer mesh around a sphere. It is non uniform boundary layer, what I mean is I am fully aware of how to create a volume mesh with boundary layers. But what I dont know is how I can create a varying number of boundary layers within the domain. Say closer to the sphere, I want 20 layers and near the inlet I need 10 layers. Is there way to create this within Hypermesh? Thanks
  6. Hi I've been experimenting with the radiation hazard zone example (Example-D04-Radiation_hazard_zones). My question is, how can I export the INIRC88_E_80percent iso-surface as mesh for use elsewhere? Is there a method to do this via a script? thanks David
  7. Hello all, I'm a beginner in HM and I would like to create a macro that will allow me to extract the mid surface of a part and after that it will mesh this mid surface. I need this for my job. I hope to be clear enough. Thank you Vincent
  8. Hi, I try to make a core shift simulation (multiple bodies) in Moldflow with boundary layers. I used the boolean operation to find the common faces and meshed them after this. The nodes look good, I do not see any intersection or failure, but in Moldflow I always get an error: ** ERROR 304717 ** A node has been found which belongs to both a part element and another element which is not in the part. This is not supported. Please check the mesh connectivity and the element property types. Does anybody know, how can I fix this? Regards, Béla
  9. Hello I just downloaded the academic version of the program. I want to mesh a part with different mesh type than the already existed. For example i want to provided the locations of the nodes of the finite element, Can hyperworks provide that possiblity? Thank you in advance
  10. 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
  11. Hello, i'm new to Hypermesh but i need to solve a problem which mush be very simple for a veteran user. I just need help on how to make a simple batch script that given and input file containing triangle surface mesh of a solid, output the entire tetra volume mesh of that solid. I'd like to do that from shell without using any gui. That's it! I would really appreciate any help. P.S. Could you please include which file format it accept as input and which as output? Thank you for your time.
  12. Hi i am finding difficulty in meshing a solid model which consists of a cube of 100*100*100 and a cylindrical hole inside the cube at the centre of body of 80mm height and base radius of 20 mm.can any one do the solid mesh for hole and the cube such that continuity between hole and cube also exists. please help me out in this asap
  13. Hi I mesh my geometry with hypermesh and use LS-dyna as a FE solver. When I created tet10 mesh in hypermesh and looked at the element summary, it said " TETRA10 ELEMENTS NOT SUPPORTED in LS-DYNA template. These elements will not be exported." I would like to confirm that if I need to export tet4 mesh and convert them into tet10 in LS-prepost. Does anyone know about the problem? I would appreciate any help. Thanks, Jay
  14. Hy everyone, I am a newbie and I am trying to get ab better understanding of Meshing in general. On that quest I have been reeding my way throught this Forum but I did only find something very specified requests of how to mesh this speciel form or size or verry general information. As I understand it, there is not the one concept that works or the one technique that is the best. But every engineer needs guidelines and general idea where a valid solution might to be found. 1. What tyypes of elements are there? 2.when do I use which elementtype? As I understood so far, this depends on: the form of my part; the kind of the analysis(stress or displacement); the elementsize i want to use. 3. How do I decide the elementsize? As I understood so far, you have do make a compromise between the numeric mistake, which is getting bigger proportional to the number of elements and therefore antiproportional to the elementsize and the mistake concluding from bigger elements and there rough not fitting shape. I realize that it sounds like I am asking for an all-in-all-solution but i really need more basic information. I would also be very happy if you link me to some helpful explenations. Thanks for any help, to be given. That beeing said I admire how productive this forum seems to be. regards Nikolai
  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. I have got a question, concerning the mesh quality. Can you please tell me, what these values, from the MeshSim.txt file are standing for?
