  1. Your post about deleting settings files helped me to resolve my problem with the panel area sliding right and off of the screen. Thank you for the information.

    Unfortunately, yes, I lost all of my settings. That wasn't a surprise, but is there a way to backup settings so they can be read in again?

    For example, I use the favorite panel, Star, a lot. I lost my collection of favorite panels. Is there a way to keep these and restore them quickly in the future?

    Thank you very much.

  2. ^HM_autoskin_2 Component

    I had two Components appear in my model and I do not know why or how they were created. The component name is in the form: ^HM_autoskin_2 The components are made of Quad elements that are the surfaces of 3-D Hex element meshes. They are the same colors of the Hex mesh components. When I export to a solver deck, the "autoskin" components do not appear in any form. I don't know if I "fat-fingered" a button without realizing it or what. I'm not doing anything I haven't done a lot before this. I am using HM v14.0 on a Windows 7 HP 8570w laptop. Thank you. Phil
  3. Why is "Assembly Browser" grayed out in View menu?

    George, Thank you very much. Knowing that, I can continue to ignore it. (Which I suppose should have been obvious.) Again, thank you. Phil
  4. When I go to the "View" menu, the "Assembly Browser" choice is grayed out. I cannot select it and enable the "Assembly Browser." Screen shot is attached. Why can't I open the "Assembly Browser?" Thank you. Phil
  5. Difference Between Feature Angle and Vertex Angle

    Very good illustrations. I think I see now. I appreciate the time you put into this. Thank you very much. Phil
  6. Difference Between Feature Angle and Vertex Angle

    I found the Tools>Features panel of which you spoke. I didn't know about it, and it can be helpful. It doesn't help with vertex angles. I appreciate your help, and feeling like I'm really being dense about this, but I'm not getting it. I have attached a screen shot of a model I am working on now. I have shown the features. Maybe you can point out or describe vertex angle from it. Thank you.
  7. Difference Between Feature Angle and Vertex Angle

    Ah wait, you said free edges. I have to think about that.
  8. Difference Between Feature Angle and Vertex Angle

    Do I understand correctly that it is the angle between the edges of two different elements? If one had a mesh of all equilateral triangles it would be a very good mesh. All of the angles will be 60 degrees. The panel came up with a default vertex angle of 30 degrees. That would require that all of those equilateral triangles be divided again. That doesn't make sense to me. Either I don't understand the vertex angle, or it should be set to something greater than 60 degrees.
  9. I am creating a triangle shell mesh for tet-meshing. When using Automesh to mesh elements with QI optimize, one can specify a feature angle and a vertex angle. The feature angle is the angle between element normals. What about the vertex angle? The manual says: " Whenever an element vertex exceeds this angle while adhering to features, the element will be split into two elements with correspondingly smaller vertices." The default angle in the field is 30 degrees. Triangles will always have an angle that is greater than 30 degrees. Someone else in the manual it is described as being similar to the feature angle. I can't find an illustration or more detailed explanation of vertex angle. Can someone clarify this for me, please? Thank you. Phil
  10. Entity Naming Convention

  11. Entity Naming Convention

    Good questions, Rahul. I took a simple model and started doing the same things to it that I've done to the real model. The model was written out of HM into an Abaqus input file. Since I do not know how to set everything up in HyperMesh for an Abaqus run, I sometimes make changes with a text editor. Then, I later sometimes read the edited input file back into HyperMesh. This morning I realized the obvious. Each time I read the file back into HM there are prefixes being added. I attached a .bmp. In the left column is the file the first time I wrote it out from HM. In the right column is the file the second time I wrote it out. Knowing what is happening, I went back to the import input file menu, but I still don't see what I have done to cause this prefix to be added. I hope this clarifies my question. Again, if you can point me to where in the documentation this is explained, I will appreciate it. Thank you. Phil HM-Naming.bmp
  12. Entity Naming Convention

    I'm using HyperMesh 12.0 and Abaqus 6.12-4. I've been away from FEA for a couple of years. My entities are now getting names like: NSET = S2;S2;S2;S2;S2;PreTensNodes and P2;P2;P2;P2;P2;FuelTank and G37;G27;G27;G32;G47;S:WashrLo Then I run Abaqus and get errors that a certain surface doesn't exist. It doesn't exist because its name got a new prefix in the model data, but not in the history data. Somewhere in the documentation I saw how names are organized between the semi-colon and colon. I can't find it now. I've looked and looked. Can someone please point me to where in the manual this naming convention is explained. Is there a way of turning it off so that I can use names like: plate, gusset, door, Fred, Wilma, Moe, Larry, CurlyJoe? Thank you. Phil
  13. Trimmed Surfaces Will Not Mesh. Look Odd

    I got sidetracked. I have an example. I will post it when I figure out how. I don't have time right now. I think I am seeing tesselation lines. I just saw them mentioned in something I read today. I didn't even have to edit this part. I usually use STEP files from Pro-E to transfer geometry. This time I tried an IGES file. It looked like this when I first plotted it. Thank you for the feedback.
  14. SimLab to Replace BatchMesher

    Well, no. Actually, I just tried again so I could tell you what the error message is and it works. Maybe I hadn't "restarted" my laptop after the installation? Anyway, it works now. Thank you for asking. Phil
  15. SimLab to Replace BatchMesher

    Is SimLab supposed to be a better version of BatchMesher? Is anyone using SimLab? (I don't see a SimLab Forum. This is as close as it gets.) I got a new computer today and had to re-install HyperWorks. I installed SimLab to give it a look, but it wouldn't even start up. Using: HW 12.0, SimLab 12.1, running on an HP EliteBook 8570w Windows 7 Enterprise, Version 6.1 (Service Pack 1) Is anyone else having better luck with SimLab? Thank you. Phil
