Dear All,
I encountered a problem when I models fluid flow through conduit surrounded by solids at two sides. The models involves laminar flow module and structure module. According to the description of reference manual, When the contact features are included in structure mechanics, the "form assembly" in geometry is recommended. So I choose the "form assembly" box. However, when I imposed no-slip BC at the interface between solid and liquid domains, and run it, the error occurs.
Undefined variable.
- Variable: comp1.spf.U
- Geometry: geom1
- Domain: 2
Form the attached image, we can see that domain 2 is solid zone, no fluid, whereas the error didn't detect fluid velocity in the soild zone. It seems weird. I try many times to resolve it but failed.
So I am wondering whether the "form assembly" in my model is the criminal. But considering the contact feature in my model (circled region in red line), I am not sure for it.
Does anyone give me some hints or suggestion on that? I will appreciate your assistance.
