I want the optimization solver to evaluate the objective at all time steps

Hello, I am using the optimization module in conjunction with the Heat Transfert in Solids and the Solid Mechanics. After computation, I always get the warning message: ' The objective is only evaluated at the final time. '

I use a Time Dependant Study and use the same time step for my optimisation Solver. My Probe Objective is the solid.disp and the Control Variable influence the HeatFlux. Since the temperature influence the thermal expansion, the displacement, the optimization solver minimize the heat flux. And it work, but I always get that warning message and I wanted the optimization solver to be able to evaluate the objective at all the time step.

Thank you.

Hi Louis,
did you find out how to evaluate the objective at all time steps?
thanks,
