Hi,

Could someone give me some idea how to solve this problem ? I want to simulate pressure drop in porous media using darcy law interface. When I use 'mapped mesh option', I can't compute it. Instead, I got below messages: (However, it works when I use 'free tetrahydral' option).

Failed to evaluate Jacobian of operator.
Failed to evaluate Jacobian of operator.
- Operator: mean
- Geometry: geom1
- Boundary: 1
Mean operator requires a meshed adjacent entity of higher dimension.
