volume regions and elastoplatic analysis
volume regions and elastoplatic analysis
(OP)
I'm having trouble getting my analysis to run. I've added volume regions to my FEA model so I can refine my mesh in the area of interest and set up both a linear and nonlinear anlaysis. The linear static analysis runs fine and completes (using the elastoplastic properties). The nonlinear anlysis tells me that there are elements which have not been assigned properties. If I supress the volume region the nonlinear analysis runs correctly. I've tried assigning materials to both the component and the volume but this hasn't solved it. Does anyone have any ideas? The whole point of a volume region

As a check can you cut away everything else except the volume region and run a simple analysis to see if it accepts material properties.

I created a bracket and performed a non-linear analysis (without a vol region)
Then added a volume region along the radius and performed another non-linear analysis and it went through fine.

after an analysis it refuses to show the results window. it works if i go to "Display Definition(s) from selection" icon and select the window, then the results window shows up.
Also, are you using any autogem setting on the volume region. If you like I can try that setting on my bracket and see.

Is it possible that your volume region is going beyond the material (by a very small amount) and hence that part of the volume region is not associated with material and its properties?

Thanks for your help.
