singular matrix error

Please login with a confirmed email address before reporting spam

Hello, I am having trouble computing the multiphysics of multiphase flow in porous media for a water electrolyzer. The geometry is configured as a half-cell. Upon reviewing the conditions, I didn't find any issues, but I keep encountering a singular matrix error.

Could this be due to boundary conditions or solver settings?

I would appreciate any help.
