Hi to everybody!
I'm writing Hi to everybody!
I'm writing a solver for the linearized euler eq., and I have some problems in the momentum eq. du'/dt + Ma & grad(u') + u' div(Ma) = -grad(p') where u', Ma are volVectorField The problem is in Ma & grad(u'), I can only discretize it like Ma & fvc::grad(u), with u volVectorField. If I try to calculate the face flux of u', surfaceScalarField phiU1 = fvc::interpolate(u1)&mesh.Sf(); and put them in grad(phiU1) I have errors. I tryied to look up and down for examples, but I can't find anything similar. What's wrong in my code? Thank you in advance! |
