Hi,

I try to solve a microfluidic porous media problem. As seen in the picture, my porous media inputs are very high. When I run the simulation, it does not converge. I've some questions for this problem;

1) Should I enter both inertial resistance and viscous resistance values or is one of them sufficient?

2) May be possible these values negative?

3) How can I solve convergence problem?

This is the geometry, and orthogonal mesh quality is 0.94

Thanks,
