    How to Assign CBUSH CID With Coincident GA and GB

    Aha! Never mind. You go into the Springs panel where you define spring elements and go into the update panel. There you can choose the orientation method and related information. Problem solved. Thank you for the help. Writing these helped me think it through. Phil

    How to Assign CBUSH CID With Coincident GA and GB

    There must be a way. I used a text editor and inserted a CID into field 9 and then read that input file into HM. When I edit that card the CID field shows up with the CID I entered. Phil
  3. The Optistruct manual says that when defining a CBUSH element with coincident GA and GB one must specify a CID. (Optistruct manual, CBUSH page, Comment 5) I do not see a way of specifying a CID in HM. Editing the element has the fields for X1, X2, X3, but the there is no field 9 for the CID. How can assigning a CID to a CBUSH be done? Thank you. Phil

    How to Change CBARs into CBUSHs

    I found the problem. CBUSHs can also be defined in the SPRINGS panel. Those take two nodes. Problem solved. One of those things you apparently just have to know. Phil

    How to Change CBARs into CBUSHs

    I have a spider of CBARs that I want to change into CBUSHs using Hypermesh. If I use the "config edit" panel it creates 1 noded CBUSHs, since CBUSHs are created under the "masses" panel. How can I make this change? Thank you. Phil Brown

    t-connection error in motionview

    I found it! In the MotionView User's Guide, in the Tutorials, in the Contact Simulation tutorials. MV-1010: 3D Mesh to Mesh Contact Simulation It outlines the mesh requirements and has a link to best practices for contact modeling. The link takes you to: MotionSolve > User's Guide > Analysis Tips: Best Practices for Running 3D Contact Models in MotionSolve. Have fun with it colleagues! Phil

    t-connection error in motionview

    I've looked in the manual for this without success. Just what is a properly meshed model? Must all geometry be meshed, or only that which comes into contact? Are shells allowed? Where does the manual tell us what the contact mesh needs to be? Thank you very much. Phil
  8. 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.

    ^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

    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
  11. 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

    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

    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.

    Difference Between Feature Angle and Vertex Angle

    Ah wait, you said free edges. I have to think about that.

    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.
