Hi, I am using Comsol 5.2 and I am trying to run a transient study.I am getting this error.Can somebody help me with this?I have defined variable D in parameters in but it still says undefined.I also have electric current,fluid flow,heat transfer equations in this model but they work fine when I disable the transport of diluted species equation.
Undefined variable.
- Variable: comp1.D
- Geometry: geom1
- Domains: 2, 4
Failed to evaluate Jacobian of expression.
- Expression: ((((-nojac(comp1.tds.v))*comp1.tds.tauScStr_c)*comp1.tds.Res_c)*(comp1.isScalingSystemDomain==0))*dvol
Failed to evaluate Jacobian of expression.
- Expression: (comp1.tds.streamline*(comp1.isScalingSystemDomain==0))*(dvol)
