In the urgent need of solving the following weak form PDE for \lambda^k
\sum_{k=1}^K \int (w \nabla . \nu^k) \lambda^k = b
where w is the test function and \nu^k are the K vectors resulting from a previous study using a parameter sweep for k.
According to the COMSOL Reference Manual I would use withsol to evaluate this expression, but withsol is not accepted in the weak form PDE, as it throws the following error:
Unknown function or operator: withsol
How can I solve my problem? Maybe via Matlab livelink?
Thank you.
