I am getting the following errors while doing simulations. While doing meshing, I did not get any error but after running the solution it showed me all the below errors. Please help!
1) No mesh on domains 1-6 in the meshing sequence with tag mesh1. This may lead to incorrect results.
2) Failed to find a solution. Singular matrix.
There are 2859409 void equations (empty rows in matrix) for the variable comp1.T. at coordinates: (8e-05,5e-06,0.00025038), (8e-05,4.75e-06,0.0002485), (7.675e-05,3.5e-06,0.00025033), (7.625e-05,3.5e-06,0.000250305), (7.625e-05,1.5e-06,0.00025038), ...
and similarly for the degrees of freedom (empty columns in matrix). Returned solution is not converged. Not all parameter steps returned.
