Hello,
I want to determine one parameter k1, which is used over the entire domain. However, objective function values should be compared only at a boundary. According to the Optimization user manual, I think I need to use “least square objective" at a boundary and either “control variable field over the entire domain” or “global control variable”. When I try these, I get an error message of “Incorrect number of coordinates in least-squares objective”. Can I define an objective function at a boundary and use a control variable applied to the entire domain so that the control variable can be evaluated over the entire domain in COMSOL? In the attached model, the Optimization module is used in Study 2.
I contacted technical support and heard that they would post a model example in the future (unscheduled for now). If you know how to do it, please advise. I'd greatly appreciate your help!
