Hi FOAMers,
I am a new user in OF and am using OF-3.0.1, I have to convert PIMPLEfoam pressure algorithm to cater for compressibilty and miultiphase mixing effect.

I am not able to understand the Pressure Equation file , I know the discreisation but am unable to understand the meaning of every line.

could you please point me in the right direction on how to learn the meaing of the line of the files of the Pimple Foam solver especially PEqn.
Thanks
GB

Hi Ali,
Thanks for the reply. I wanted to relate the concept behind various functions used in pEqn but was unable to do so. I tried the book you mentioned but was unable to find any explanation for various terms.

Hi
Start from section 11.2 p.114 in that book.
Also try to make a review to the earlier solvers of version 1.6.
