How can we assign a initial temperature to a wall in Ansys Fluent?

If we assign it in boundary conditions in fluent , we know it will treat it as a constant. But if wall is initially hot and cools by convection ( means not constant temperature) how can we treat...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
