Parrafin Melting - Scale Problems
My simulation consists in melting paraffin inside a heat exchanger using hot water (geometry is bellow). Initial conditions of water inlet temperature at 52?C, flow rate at 1.5l/s and the paraffin initially at 18?C.
My first step was to validate my model with an published article, and using real scale it works but took more than one month simulating to finish.
Now, I want to reduce the model scale to do all the tests I need. I reduced scale (x,y and z to 0.5) and now I received this error "Stabilizing temperature to enhance linear solver robustness." and the model is not converging anymore. I attached the summary with the methods used.
Can anyone help me?
