  1. Hello, I have a model that has already solved for stress/displacement analysis. Now, I have particular spots to look into more closely. I know there is a group feature that allows element grouping, but with this feature, can I see the assigned group and the results (particular elements in my structure) in hyperview? I'd like to set those particular elements and see how the stresses change as I make structural modifications.. If so, please tell me how to apply this. Thank you.
  2. Hello, I'm searching for an easy way to implement the following constraint for a group of design variables in an optimization study within the Hyperstudy interface. Let's assume we have the variables A, B, and C wich should be varied within the following ranges: A: Lower Bound: 0, Upper Bound: 1, Initial Value: 0.33 B: Lower Bound: 0, Upper Bound: 1, Initial Value: 0.33 C: Lower Bound: 0, Upper Bound: 1, Initial Value: 0.33 Whereas the general constraint A+B+C<=1 musn't be violated. My approach using the function "Link Variables" did not lead to an appropriate result. I would like to avoid a redefinition of the parameters within the solver input file (i.e. by A = A/(A+B+C), in consideration of the explicit assignment between the parameters defined by Hyperstudy and the "real" parameters used within the solver. Does anybody know of an convenient way to implement the constraints as described? Thank you for your efforts in advance. Cheers, Felix
  3. Hello, How can i see results for a particular component in a big assembly? I know i can just Turn off all the components/elements and show only that particular component to see its results, but i have quite a few iterations and quite a lot of components to carry out this operation. So every time doing this is a painstaking process. So instead i would like to create a few groups before running the analysis like we have elements assigned in Assembly Hierarchy. So while Post-Processing i can directly Turn ON/OFF a particular group to check results. Then saving as the file will also retain the groups for further study and post-processing for other iterations.
  4. Hello guys, first of all, I'd like to thank you for your great support. I'm quite new to FE analysis and now i'm facing my first problems. To get known to HyperWorks, I started to mesh an imported CAD file with Hypermesh and defined materials and properties. Before applying Boundary Conditions and forces I wanted to check the model for errors and started the anaylisis ( Solver: Radioss (Block 140)) That's where I encountered some error messages. With the help of this forum I was able to fix some problems. For these messages I wasn't able to find any solution: According to that warning, i found a thread here ( http://forum.altairhyperworks.com/index.php?/topic/19028-warnings/#comment-39612 ) Unfortunately I couldn't help myself to fix that issue. For which criteria I have to check the surfaces? What's to do to fix that error in element group? Regards
