Energy equation in RhoPimple solvers
 

Hi,
Does anyone know where the Energy equation is solved in rhoPimple algorithm?
From what I understood, the algorithm "chronological order" is the following:
1- Pressure is guessed
2- Momentum equations provide Velocity
3- Velocity is inserted into Mass equation to provide Pressure
4- Pressure is used to correct Velocity
Then, the cycle restarts.
In some books, I read that Energy equation (to provide Density) is solved between steps 2-3, while in other books I found that it is the last step (after step 4).
Most likely, something is missing in my reasoning.
Could someone help me, please?
Thank you in advance,


Tommy M.
