  1. I just figured it out. There is a multiplier option that take care of the issue only for visualization. see attached. Thanks, Maysam
  2. Hi everyone, I have a question that I'm sure the answer is no but I thought maybe someone knows a workaround for it. I was wondering if it's possible to show the legend in HyperView (see attached) in another unit? I don't want to change the unit of my whole model but just want to somehow show the stress unit in the legend (which is in MPa right now) in ksi only for the sake of presenting it to certain groups of people. FYI my solver is ABAQUS. Thank you, Maysam
  3. Even when I just use the "Build Plots" button in HyperView then select what I want to be plotted for a specific element, it just doesn't plot anything :/ The time history shows the change of von Mises correctly and I just want a simple plot of it versus time! I'm really confused! What am I missing!!?
  4. I'm trying to plot an element's von mises stress vs time but mises is deactivated when i want to choose it for y-axis. I'm new to HyperView. Could anyone help me figure this out? Attached screenshot shows the issue. Thanks, Maysam
  5. Exactly!! The partial remeshing brings up the problem. I just remeshed the whole part again and it went ok but the moment I try to fix the problematic elements (like tetra collapse or aspect ratio) by remeshing them, it just messes everything up again! I think I finally go with Rahul's idea of doing it with hexa mesh.
  6. Yes Rahul, I know about hexa mesh transition but it needed more preparation also the mesh is not in a critical location and only will transfer the stresses/strain so I decided to go for tetra. But you're right hexa transition is much better and more reliable.
  7. I was wondering why I get some messed up mesh (and consequently some free faces flying around, marked in the screenshot) when I use tetra remesh to take care of tetra collapse and other element check factors. I need to mesh the transition layer you see in the attached screenshots. When I tetramesh it, it's ok and no free edges/faces. But after remeshing the tetramesh locations with problematic tetra collapse, I end up with some weird elements protruding to others and some free edges/faces that even equivalence couldn't get rid of them! Any help/idea is greatly appreciated. Also let me know if you know a better way to mesh this transition than tetramesh (the area of the inner squares are 1/4 of outer squares). Thanks a lot, Maysam
  8. Great! Thanks @Q.NGUYEN-DAI for sharing the script. I'm still learning tcl and was kinda struggling to do what you did this fast Any recommendation about learning tcl would be greatly appreciated!
  9. Thanks, here's mine. I made this using split (shift+F6) but the problem is in HM13 it only works one element at a time (in one direction each time). Hopefully in later versions of HM, they make it work for multiple elements. hexa-coupled-split.inp
  10. Quick question... in the original Trelis model, they used those elements that I enclosed with red lines (see screenshot 1) but in the mesh that I made in HM (screenshot 2), I didn't put them and still gave me a pretty nice transitional mesh (at least it passed all the element checks). Do you think those layers are necessary? I haven't run the model in any way and just wondering!
  11. Nice! I was also working on different alternatives... I got this:
  12. Yup me too! I wish we had its file. It would be awesome to back track it and make it with HM Gonna ask around to see if anyone has/used Trelis and let you know if I got my hand on that mesh.
  13. Unfortunately I don't have this mesh because I don't have Trelis. Here's the link to the image I posted: https://cubit.sandia.gov/public/14.0/help_manual/WebHelp/mesh_generation/mesh_modification/mesh_refinement.htm#drawing I wonder why HM doesn't have this ability for hexamesh (or it has and I'm missing it)!! This hexa mesh makes much more sense compare to the automated tetramesh in HM!
  14. This is a mesh refinement from Trelis. Is it possible to do this in Hypermesh (auto or manual)? If so, how? Thanks trelis.ts
