we I set the assemble part as a union, i get an answer. but when i set it as assembly, it goes wrong and says "Failed to find a solution. Singular matrix. For mesh-case 0 there are 11217 void equations (empty rows in matrix) for the variable comp1.T. at coordinates: (0.0467139,0.055,-0.00210548), (0.0461079,0.055,-0.00176786), (0.045502,0.055,-0.00143024), (0.0461536,0.055,-0.00248168), (0.0455401,0.055,-0.00214454), ... and similarly for the degrees of freedom (empty columns in matrix). There was an error message from the linear solver. Maximum number of intermediate iterations reached. Returned solution is not converged. Not all parameter steps returned." How can i deal with this? I just do a thermal simulation.
