How to converge continuity in archimedes screw simulation?

16 July 2021 1 8K Report

Heloo All,

I am doing simulation about archimedes screw turbine with ansys fluent. But, the continuity do not converge. It always increasing and become floating. The boundary condition is same like the teory. Any suggestion all?

Thank you very much

Did you try to reduce under relaxation factors at the beginning of simulation? If not, try it.

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
