potentialFoam solverHello,
I am confused about the basic potential foam equation in OF Code:
`fvm::laplacian` b) Is p really pressure or velocity potential ? If it is velocity potential , then it would not require the rhs (i.e laplace(psi) = 0). Are we trying to solve stead-state euler equations Or the laplace equation for the velocity potential ? I am really confused about this. please reply. thanks |

I have finally understood the algorithm after weeks of searching! But this board is the most unhelpful discussion board I have ever come across by far.
Just in case some one has similar difficulties understanding the algorithm , I don't want you to go through same diffculty so here it is. * It is first of all solving the laplace equation laplace(psi) = 0 * There is a "hack" in createFields.H that zeros both p and U in the internal field so that only the U at the boundary will be used as a source term for the above equation. The odd placement of that code in createFields.H was the main problem for me. Here is a link to the document that explained to me how the solver works. Thanks to the writer. |

Hello everyone ,
Please let me know how to calculate the total pressure field (= static p + dynamic p) in case of potentialFoam. i used potentialFoam -writep. i have a doubt if p is actually p or something else. Thanks in Advance, antony |
