Volfrac or Massfrac Error in topology optimization

Anıl Türkseven

Hello everyone,

I have a problem. If you help me, I will be contented.

I want to make a topology optimization and My objective is to minimize massfrac. However, I got an error every time. How can I solve the problem?

I think everything is correct. I checked one more time.

I have shared the files of the program. Can you look at the definitions?

The problem is your properties : All your model is "NonDesign" and you have no elements with the "Design" Property applied.
You need to reorganize your model to have elements correctly distributed between your two components (currently all FEM is in on component).
Use the "Organize" tool to transfer elements from one component to another.

Hello Anil,
The error message you get says you did not apply the Volfrac response to a propoerty that is covered by the topology design variable.
What parameters did you use to define your VolFrac response ? Did you use "all" ?
If not you will need to select the property(ies) you want to evaluate the volume change from, and this(those) need to be also in the topology design variable.
