Tips on running cases with interFoam
 

Hello Foamers,


I have just started using interFoam. I have some questions I would appreciate some help with.


1. When running cases with interFoam using the pimple algorithm with momentum predictor active, can I use relaxationFactors? Will they distort the physics if used?

2. In some of may test cases, the simulations diverge in the first time step. However, if I use setFields to fill the first layer of cells near the inlet, the simulation runs smoothly until the end. Is this a valid approach?
