Deardorff LES

Roman1 · January 15, 2018, 03:57

Hello all. I am tryinng to run simulation with DeardorffDiffStress LES model. At the first time step, after Ux, Uy,..., rho are solved, a notion appears: incompatible dimensions for operation [R[1 -1-3 0 0 0 0]]- [R[0 -2 -3 0 0 0 0]]. R dimention is [0 2 -2 0 0 0 0]. Please help to fix this problem. Thanks.

Changed string 196 in the file DeardorffDiffStress.C:
earlier: - fvm::laplacian(I*this->nu() + Cs_*(k/this->epsilon())*R, R)
now: - fvm::laplacian(rho*I*this->nu() + rho*Cs_*(k/this->epsilon())*R, R)
it seems working ОК.
Thanks
