Dear everyone!
The time evolution equation of the reynolds stress tensor R_ij = bar(u_i*u_j) is described as follows; //----------------------------------------------- tmp<fvSymmTensorMatrix> REqn ( fvm::ddt(R_) + ... //----------------------------------------------- I would like to implement R_i1 = bar(u_i*u_1) and R_i2 = bar(u_i*u_2) into the equaion, how should I write? (bar(u_i*u_1) = bar(u_i*u_j)*δ_j1 ? where δ_ij is the Kronecker delta) Would you be able to help me? aki Last edited by aki_yafuji; April 16, 2011 at 07:51. |
