Replies: 13 Conjugate Heat transfer for Incompressible Fluids Views: 4,091 Posted By Bloerb If you do not know what a relaxation factor is,... If you do not know what a relaxation factor is, you should not do numerical simulations. That is the harsh truth. The more modest response would be to not touch them, since the standard values are...

Well you need to set a maximal and a minimal value that could occour in your simulation. For example 0 and 10000000000000 would suffice. Setting closer ranges might make it more stable during start...

Yes, if rho is set to constant your flow solution does not depend on temperature. If you want to simulate something compressible you need to switch from rhoConst to e.g perfectGas or one of the many...

Well heat transfer can happen by natural and forced convection inside a liquid. Lets look at how this effects the motion of the fluid: \frac{\partial \rho\mathbf{v}}{\partial t} +...
