When I run simulations with Boundary Conditions set to "Dirichlet (V)" it works perfectly. However, whenever I set Boundary Conditions to "Flux" (A/m^2) instead of "Dirichlet" (V), the analysis shows any E or J results as zero. Not sure what I am doing wrong... has anyone had the same problem?
What is the error message indicated by the red triangle? Maybe the flux is negative. Did you try adjusting the limits on the colorbar?
