I am trying to model wicking of paper in 3D, by following the tutorial for paper wicking in 2D on the COMSOL Application Library , but ran into this error:
Undefined variable.
- Variable: phtr.pc_s2
- Geometry: geom1
- Boundary: 3 Failed to evaluate Jacobian of expression.
- Expression: (comp1.p-comp1.dl.p0)*dvol Failed to evaluate Jacobian of expression.
- Expression: ((comp1.p-comp1.dl.p0)test(-comp1.p_lm))(dvol)
Attached is the file for everyone's reference.
Does anyone have any idea how to solve this?
