Hi,
I have an issue with a phase field model which contains two fluids and a structure. I would like to see the effect of fluids on the structure. However, I am not sure what I am doing wrong and receiving the error below.
I followed this application https://www.comsol.com/model/two-phase-flow-with-fluid-structure-interaction-4515
Undefined variable.
- Variable: comp2.pf2.u_primez
- Geometry: geom2
- Domain: 3
Failed to evaluate Jacobian of expression.
- Expression: dvol_spatial*(r*(pi*(2*(comp2.pf2.res_prime*(-(comp2.pf2.u_primer*comp2.pf2.tau_prime))))))
Failed to evaluate Jacobian of expression.
- Expression: (2*comp2.pf2.conservationCompensation*pi*r)*(dvol_spatial)
I'd highly appreciate any recommendations.
