The assemble feature assembles the matrices specified as output matrices and stores them in the feature. The output is stored in the feature. You can access the result using the matrix and vector access methods. The linearization point is determined by the current solution (that is, the solution computed by the previous feature in the sequence). The linearization point is stored in the sequence after the run. For information about the eliminated system, see Advanced in the COMSOL Multiphysics Reference Manual.
