Hi, I got a bit of help and will post the answer:
In my model I posed the constraint on a node that will not have much movement and also my constraint was far too easy to meet. While it may sounds like it may help, the program seemingly doesn't know what's needed in the solution.
I changed my...
Hello,
Sorry it is my third thread on the subject but I was unable to find the answer anywhere.
I run my optimization and the log ends on a positive note:
"OPTIMIZATION HAS CONVERGED.
FEASIBLE DESIGN."
Yet, in Hyperview no matter the iteration the density of my elements is never close to 1...
Hello,
I found out that when implementing my displacement constraint I had forgotten to link it to my loadstep. Once I linked it my model worked.
If anyone reads this with the same problem, my model did not work without a displacement variable and constraint.
Well in the example there is a component named rbe2. I am not sure how I placed a constraint on rbe2, so how would I go about not placing a constraint there?
I uploaded my carm example on rapidshare if anyone finds it simpler to find the mistake that way...
I mostly followed the same step as the A arm for my own problem and seemed to get further without error so I continued with it.
I also tried it with a displacement constraint, but still got a empty design volume from the first iteration.
I tried 3 times, following the exact instructions provided, but I ended up with the following error when running Radioss or Optistruct:
Created RAM scratch area: total size 200.00 MB

Hello,
I want to do a topology optimization on a design volume with 3 other volumes being non-design volumes. All loads and constraints being on the non-design volumes. However I seem to be running into a problem setting up my optimization, I would be most grateful to get some help.
I setup my...
I imported Step geometry from Catia, so they are solids without mesh.
After importing the volumes are already made. I will try both those options and see what happens. I'll keep updated on the results, thank you very much :)
So...
I did tetramesh part by part... are you saying I should 2D automesh all my parts then 3d automesh all my parts in order to get it to stick together?
Hi,
I imported 4 components into hypermesh, but they aren't attached together in any way in hypermesh.
I want to realize a topology optimization, but I cannot get them to attach together, a teacher told me I have to merge the nodes in the surfaces that connect the components, but I am at a...
