Sandwich Analysis
Altair EmployeeHi There ,
I'm engaged in the project of chassis design for a vehicle for the FSAE competition and i have to make the chassis with a sandwich (CFRP - Foam) material , since hyperworks (OPTISTRUCT) will help doing the analysis , i started making a plate and making plies with CFRP (MAT8) and PCOMPP card image then a Core(MAT1) with PSOLID property , also i make laminate with the plies . i applied the load with constrains then loadstep with both and i check CSTRAIN and CSTRESS Properties for the analysis but since i start the analysis there is no iterations made and only the one displacement result appear , i tried alot to change in the structure but still no iterations ,
Here is what i have and there is a copy of the hm file attached
The Results
Iteration Subcase Variable Grid/Elem ID Value
---------------------------------------------------------
0 1 MaxDisp 12205 -0.285887E-02
0 1 MaxStress 5725 -15.0120
The amount of memory allocated for the run is 331 MB.
This run will use in-core processing in the solver.
ANALYSIS COMPLETED.

I've changed only the magnitudes of the loads and then when i run the optimization analysis i got the same thing again , i attached an image of the results also

Hi mmramadan,
The analysis is completed and you can view the results.
I don't see any errors
