  1. Hello, I couldn't distinguish between intersection and penetration. In the model (image in the link below), i could see the penetration of elements, still the penetration check tool shows no penetration, only intersections. My doubt is whether penetration is checked only with certain normal angle? https://drive.google.com/file/d/0B2rIYPnVjYNESWxNcVdveExXSW8/view?usp=sharing Ahilan
  2. Thanks for the reply. I use HV 12. So the problem is with the version.
  3. Hello Prakash, Filedrop is not working. Is it ok if i upload in a external server (Google drive) and share ? Ahilan A
  4. Hi Anyone please clear my doubt. Ahilan A
  5. The following is the vonmises stress contour plot i get in a component with predominant bending load. https://drive.google.com/file/d/0B2rIYPnVjYNEVjdfcHNQTjBXNVE/view?usp=sharing I get discrete distribution concentrated at each elements. (I used 10 noded tetra). What could be wrong here ?
  6. Where can i find the Output Request Expression Syntax details for MV ? (Documentation only seems to explain the general mdl format for output)
  7. Is there tool / procedure to check any interference of mesh of two different components ? Ahilan
  8. I get the following error when i setup the model in Abaqus proile and convert to optistruct profile. It shows ontact surfaces not selected. But the conversion tool don't ask for any surface selection. Error Snap in the link below https://drive.google.com/file/d/0B2rIYPnVjYNEeGo4TDg1NUJqNzg/view?usp=sharing Ahilan
  9. When i create only nodes (no mesh) in HM, and i import to MV. But the nodal points didn't get transferred. what approach to follow ?
  10. I will only do rigid body analysis. In that case, only the surface 2D mesh for a 3D solid body is enough ?
  11. Is it possible to measure contact pressure / pressure distribution between two rigid bodies in motion using MV?
  12. How to define point anywhere in the imported CAD ? Imported CAD body seems to have random mesh. And its only able to choose / define points in those particular nodes. How to refine that mesh Or is it has anything to do with CAD exporting / settings ? Note: i use MV 12 Please find the image below. https://drive.google.com/file/d/0B2rIYPnVjYNEMlk2cGVIOFI0Wlk/view?usp=sharing Ahilan
  13. What is the actual purpose of loading .tcl file before importing coordinates?
  14. How to request max principal stress output in each integration point ? I need to have the corresponding numerical value of max princial stress at all integration point in a model for plotting. Note: I solve in abaqus.
  15. How to create any contact surface from the given menu (image) attached below https://drive.google.com/file/d/0B2rIYPnVjYNESUFvQXVGaVZsX0U/view?usp=sharing Here is the problem i want to get resolved https://drive.google.com/file/d/0B2rIYPnVjYNEdkVKNmxyWHN1WWc/view?usp=sharing Note: I use abaqus for solving
  16. How to define surface to surface contact (not surface to suface of element) in HM?
  17. Thanks. Now is it OK if i delete " Element size control " (in the component list) ?
  18. I want to refine the mesh in certain portion of a surface and used refinement box option. But it refine only the interior elements and keep the surfece elements same. How to refine the surface using refinement box or is there any better option i can use ? Image attached. https://drive.google.com/file/d/0B2rIYPnVjYNEbGY5TkNHRUhtSFE/view?usp=sharing
  19. Actually i ll solve in abaqus and mesh in HM. In the assembly i analyse, there are two different components; one is of very high stiffness compared to other. so i want to define that component as rigid. In abaqus while creating a component we can define as rigid. but my component is of complex shape so i mesh in HV. Once i take to abaqus i cant define as rigid for the component imported from HM. So i want to define the component as rigid in HM itself or any other trick?
  20. Hi Rahul, I have only access to hyperworks 12 in my Lab. Will the feature be available in Hyperworks 13 student edition. (if yes will i be able to open a model with more than 10000 nodes in hyperview student edition ?).
  21. (like in abaqus) so that no need to mesh;
  22. I want to apply centrifugal loading to a thick rotating disk (Body force = density *angular velocity ^2* radius). If it is first order element i can equally share the load among each nodes ( lumped body force vector for linear approx ). But it is not correct for second order elements (consistent body force vector for quadratic approx). Then what would be the correct way to apply the loading (other than sharing the loads to nodes , is there any way to apply the loading to the whole body at single step ).
  23. I want to apply torque to a small protrusion from the component. But Solid elements don't have rotational degree of freedom. So how to apply the torque ( Torque needs to be applied on all the surface nodes of the curved area ).
