To determine the compliance for each iteration in topology optimization

Hello everyone, 

I am running a topology optimization simulation and would like to determine the compliance for each iteration. It helps me to have a criterion for the further steps after the optimization. Does anyone have an idea? 

Reduction of weight is goal and yield strength of material is defined as constraints. I need to monitor the changes of compliance during optimization. No matter on the graph or as results in output file

Thank you very much for your help
