Constraints in multi-material topology optimization

Hello everyone, 

I would like to carry out a multi-material topology optimization. Yield strength of materials are constraints for me and minimize weight is objective function. My problem is that how can I define yield strength on properties when I have no idea about distribution of materials in design variables. in Altair examples I have seen that displacements are defined as constraints but I don't have a criterion just like Altair examples. 

thanks for your help

    Hi Reza, 

    Currently a material based stress response is NOT supported.  It will be supported in further version. 

    Stress responses based on property or element entity is supported as you may know. 

     

    Thanks and best regards.
