solution not satisfying equation in PDE module

Please login with a confirmed email address before reporting spam

In some examples in a PDE module, e.g. ut=f(u), postprocessing data suggests that the LHS=RHS isn't satisfied, that is ut differs from f(u) by a significant amount (where ut has been collected by comsol itself as time derivatives during the solution already). Anyone came across this?
