Analysis from Ossmooth

Altair Forum User

Hello,

I'm a beginner with hyperworks and topological optimization and I have difficulties to start an analysis with my OSSmooth result. I've made a part optimization which have been working well and from this part optimization I've generate a new mesh with OSSmooth. Now I would like to know what are the constraints and the displacement in my new geometry, that's why I would like to make an analysis with this result but when I start the analysis, optistruct tell me that there is an error #1000 : incorrect data in the field #3. You will find attached the message. Could you help me to find the problem?

Hi Camille,

Please make sure you have assigned material and Property to the component and run the analysis again.

Thank you

Hi,

Thank you for your help, I finaly fixed this problem, I had not selected the right option in the Ossmooth (Geometry instead of FEA Re-Analysis). But I've got an other problem : when I run the analysis I've got the following error : PROGRAM STOPPED: ERRORS DURING ELEMENT QUALITY CHECK.

I've found that you can desactivate quality check from: CONTROL CARDS ---> PARAM ---> CHECKEL ---> deactivate CHECKEL_V1 but I can't find it in the software... Also I use Analysis and not reanalysis in the Analysis/optistruct menu, I've try to use reanalysis, the job is completed but nothing appen after. I don't know which one is the most appropriate.

Analysis is the right one. You did it right.

Thank you

Hi,

Try to change the name of the analysis. Sometimes, it does happen that analysis runs but nothing comes up
