Hi,
Is it possible to assign different isotropic materials with Psolid property to a single component? No assemblies , just one component. If yes, could you please tell me the process?
Thank you
Yes, instead of assigning property to component, assign to elements.

Hi thanks for the quick reply. I tried it. I get an error message:
*** ERROR 14: Missing property # 1 referenced by CHEXA # 301. what does this mean?
Sorry about this but im a beginner at using optistruct. Appreciate your help a lot!
Please make sure you use PSOLID property for solid elements...
What type of property are you using for solid elements?
Using only Psolid.
Sorry found the problem. Hopefully I get the result Im hoping for.
Thanks a lot for your help!
I tried to use the model checker. It gives a warning of unused property . Is this normal while using more materials for a single component ? Or have I done some mistake again? Also, is there any way of knowing in the post process where which material has been used?
Thanks a lot
Hi @Kate
Not sure how you are modeling. It is possible to have different materials on a single component. But for this, you need the same number of properties as materials.
I should leave the component property unspecified, assign the properties to all elements and just add all the properties created to the list of properties in dtpl card . This is the procedure right?
Is it possible to share the model?
Please use the file transfer link in my signature to share the model file
Hi Prakash,
I tried it with the MMAT format and I got some results. But I do not know how to interpret it . I get the result type as
1. material and
2. element density.
I know what element density result type is but with the material type, it ranges from a value of 0 to 4. I have considered 6 materials for the optimization.
Could you please let me know what it signifies?
Best regards
Kate
Can you post an image of MMAT and results from HV?
Do you see .hm.ent.tcl/.hm.comp.tcl in your working directory?
•.HM.ent.tcl contains the sets of elements for each material
•.HM.comp.tcl contains the components for each material
Thank you for all your help on the MMAT format. I was able to find the files in the directory just like you suggested. And it worked.
But would you mind helping me further regarding the reanalysis? Is it possible for me to use the structures from the .hm.ent.tcl/.hm.comp.tcl and perform a reanalysis on it? How can i see the stresses acting on these structures?
Thank you!
After updating with the tcl, you can re-run the analysis for validation.
ok thanks a lot!
