Hollow fiber membrane

Please login with a confirmed email address before reporting spam

I want to model hollow fiber membrane, I have a problem with reaction term in tube side. this term changes the continuity equation into nonlinear type. this model has three section; tube, membrane and shell. unfortunately, NO CONVERGE! do you have any idea? or experience about this type of model.

Thank you.
