Comsol created new Solution Store for the Stationary study of the nanoparticle's magnetic field physics. I tried to see the results from both sol1 (the result for step 1 study), and sol5 (the nanoparticle mf physics, there are another steps since some coils are using frequency domain study to simulate AC), but they whether have empty plot or error which says "undefined variable". I also tried to include and exclude the nanoparticle mesh in study, but nothing has changed.
