Hi,
I have started to use FEMLAB recently and have some problems. Anyone knows about FEMLAB??? I am using the PDE Modes,Weak Form Subdomain to analyse the flow over a topography. I have implemented the lubrication equation in the subdomain settings but I have some problems when solving it. Can anyone help me please. Thanks a lot |

"Anyone knows about FEMLAB" I made some few trials with solving N-S equations with COMSOL.
"I have some problems when solving it" Could you give some more details about the problem ? Does the nonlinear iterations diverge, or the linear solver fails ? |

Are you sure that the flow is laminar? Check the reynolds number first, if it's too high use the K epsilon model instead of NS.

hello, does anyone know what the best solver for the Comsol model ke? For low fluid compressional why the pressure is almost constant?
