  1. 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.

    Unable to view mesh

    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!
  3. 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!
  4. I have a multi-volume model that has bodies representing welds that share surfaces and edges with the welded bodies (volumes). One one side of the welded plate, the fillet volume match meshes perfectly and on the other side the mesh fails to match on at least one shared edge. Since there is no "equivalence" tool that I can find, how do I create a mesh control that enforces a matched mesh at the shared edge? I've added an edge control to the upper "unmatched" edge but the same unmatched mesh is created. This issue occurs regardless of 2D or 3D mesh so it may be geometry related but I'm not confident right now that changing the geometry will solve the issue. Any help?
  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

    Export iso-surface mesh

    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, Does anyone have a good step by step method of combining multiple components and their loads? I understand the concept of first creating a 2-D shell and then a 3-D (for me, tetra) mesh to finalize a component. My specific problem is that I am trying to simulate fluid flowing through a solid (like a pipe of water through a cube). My partner does the CAD, and he gave me two IGES files of the components (one being fluid, the other being metal). The IGES files for both are just the "shell" surfaces for the two. I imported both geometries and began meshing. I created a 2-D mesh for the fluid, and one for the metal. Then I went to do tetramesh for each. I used the option "per-volume-component" to create a solid mesh for the fluid and the metal separately. If I wanted to specify a constraint on the fluid shell nodes but needed it to interact with the shell and solid elements of the metal...how would I go about that? Does it do it automatically? This is where I'm stuck, so if anyone has any advice or can direct me to some help, I'd really appreciate it! Thanks. Dylan Stelzer
  9. 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

    Rigid Body Mesh

    Hi everybody I would like to create a rigid mesh on the surface of a body, because i need a rigid body, for which are not calculated stresses neither strains. Could i mesh this surface using "rigid body mesh" panel in automesh panel? if it is the way, the mesh created will be used just to compute other things like interfaces reactions or others, and the mesh created will be completely rigid ... i'm i wrong? thanks

    Different Mesh Type

    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

    Issue with VWT

    Hi, I am very new to Virtual Wind Tunnel and Hyperworks in general, been at it for a mere few days, so my issue may be incredibly basic. My issue; I am using Solidworks to create a car model assembly, importing that into Hypermesh and meshing it. Everything seems to go correctly here. I am then importing the meshed file into Virtual Wind Tunnel, setting everything up and running the simulation. My issues comes with the results; it is 'seeing' my model as a number of dots/mesh elements, not as the whole model (I have attached a screenshot, poor quality but it gets my issue across). This could well be an issue with my model or meshing but I really have no idea. I have tried lots of things over the past couple of days to no avail. Any help would be greatly appreciated. Tim

    Geometry clean up

    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

    Mesh wing model

    Hi all, I've been trying to get a wing model from HM to VWT. I've been told that the body I've created thus far is correct (see bottom of post). What I've done is clean up the geometry and created a solid from the bounding surfaces. However, no matter what mesh I create (surface deviation, CFD tetra, etc) when I import into VWT (CFD>Nastran Fluent) there isnt one single volume but four separate ones. This seems to fail when I run the analysis. Can anyone point me in the right direction. Regards, A. John Baker HM wing model: https://www.dropbox.com/s/5hqmijj3ifwkdi6/defeatured_model%20%281%29.hm
  15. Whenever I edit surfaces, especially trimming, I end up with surfaces that look translucent with strange lines going across it. If they mesh, they sometimes look like one surface on top of other with different meshes. How can I avoid this? Thank you. Phil

    Tetra volume mesh script

    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.

    Regarding solid mesh

    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

    tet10 mesh in LS-Dyna

    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
  19. 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
  20. 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
