I have created a tube in tube geomtry for adsorption of gases. This is error I'm getting after computation. Can anyone help in this?

Undefined variable. - Variable: comp1.mat2.def.pA - Geometry: geom1 - Domain: 3 Failed to evaluate Jacobian of expression. - Expression: d((comp1.ht.hs1.Qtest(comp1.T)comp1.ht.d)(dvol_spatial),{test@3}) Failed to evaluate Jacobian of expression. - Expression: (comp1.ht.hs1.Qtest(comp1.T)comp1.ht.d)(dvol_spatial)

It shows that density of gas is pressure dependent and it does not find the pressure in the domain. Make sure you have fluid domain
