Dear Foamers
Looking at solidParticleFoam I didn't understand what the code in hitWallPatch (in solidParticle.C) is supposed to do, it looks like it just inverts the direction of the particle?? Code:
vector nw = wpp.faceAreas()[wpp.whichFace(face())]; nw /= mag(nw); scalar Un = U_ & nw; vector Ut = U_ - Un*nw; if (Un > 0) { U_ -= (1.0 + td.spc().e())*Un*nw; } U_ -= td.spc().mu()*Ut; Code:
vector n = wpp.faceAreas()[wpp.whichFace(face())]; n /= mag(n); U_ -= 2 * (U_ & n) * n; |
