Hello everyone!
I'm a new entry in thi forum and I need some help with Comsol multiphysics.
I'm creating a model of tsunami waves propagation in a defined domain using the PDE interface.
I ve not problems in stationary case, but when I try in time dependent case Comsol give me the error: error in evaluating a variable Jacobian
Someone can tell me how can I resolve this problem?
I would be very grateful!

Thanks to all

Hi,
I have the same problem with COMSOL V4.0a. I'm wondering if you found any solution for that? Do I suppose to use MATLAB optimization toolbar in this case. If yes do you know any example that can help me to solve my model using optimization toolbar in MATLAB?
I greatly appreciate you help,
Atieh
