ooo Member Join Date: Feb 2012 Posts: 49 Rep Power: 14	In the icoFoam , simpleFoam and ... we have the UEqn as below : Code: fvVectorMatrix UEqn ( fvm::ddt(U) + fvm::div(phi, U) - fvm::laplacian(nu, U) ); (Afterwards, The UEqn.H() and UEqn.A() coefficients are used for pressure correction.) My question is : Does the H() and A() coefficients depend on both time and spatial descritization schemes? or they only depend on spatial schemes?
