Using the snGrad operation -- CFD Online Discussion Forums

WebAug 2, 2006 · The first parameter of fvm::Sp should be a volume scalar field. In your operations you use fvc::snGrad (pow (k_,0.5) which is a face-normal gradient of k^0.5 (why not sqrt k?). A face-normal gradient is defined on the faces, and you cannot sum up a cell centred and a face centred field. WebMar 6, 2013 · Prior to this version of OpenFOAM, the form of convective derivative was hard-coded into transport equations. In version 2.2.0, we have introduced a bounded form of discretisation which, when applied to a convective derivative such as fvm::div (phi, h), will include a component for the -fvm::Sp (fvc::div (phi), h) term. can mods give themselves channel points https://procus-ltd.com
