Dear all, Hoping all is doing well. I've built a simple model for thermoelectric generator 2D, but i have an error during run the model related to singularity matrix. Also i have a union in Definitions and i need to make sub union. Can you support me??? Failed to find a solution. Singular matrix. """"There are 1 degrees of freedom that do not occur in any equation (empty columns in matrix) for the variable comp1.Qavr. at coordinates: (0,0), ... There are 1 degrees of freedom that do not occur in any equation (empty columns in matrix) for the variable comp1.Qmax. at coordinates: (0,0), ... Returned solution is not converged. Not all parameter steps returned."""""
