I want to use COMSOL simulation on Global Optimization Toolbox of MATLAB.
I tried to optimize control point of bezier curve (as design variables) in COMSOL model by using Genetic Algorithm (Global Optimization Toolbox of MATLAB). So I tried to use LiveLink for MATLAB and Grobal Optimization Toolbox.
Then, MATLAB returned this error "Undefined variable "ModelUtil".
"main.m"(excerpt) 〜〜〜〜〜〜〜〜〜 gamultiobj(@evaluation,nvars,A,b,Aeq,beq,lb,ub,nonlcon,intcon,options) 〜〜〜〜〜〜〜〜〜
"evaluation.m"(excerpt) function obj = evaluation(x); %%% x is control point of bezier curve, obj is objective value
〜〜〜〜〜〜〜〜〜 model = ModelUtil.create('Model'); 〜〜〜〜〜〜〜〜〜
I expected that I can do gamultiobj successfully.
Parallel computing option : true I attach import com.comsol.model.* and import com.comsol.model.util.* and addpath of mli definitely. Moreover I do mphstart with parfor (I confirm that mphstart is completed because simply calculation with COMSOL is completed).
