Hi,

I was wondering how should I define new stress tensor for N-S equations? I am working with Liquid Crystals (LCs) and I'd like to solve its flow motion with COMSOL, the problem is LCs has different form of stress tensor and I want to plug in the new one in N-S equations.

Cheers

Did you figure this out? I am also having trouble in calculating the stress tensor based on a velocity data.

Dear Nader
Did you find what you want? I also need to add additional stress tensor (of electrostatic) in N-S.
Many thanks
Ahmed

Dear Tyler
Did you figure it out? I need to add a maxwell stress tensor in N-S equation.
Thanks
