FEM discretisation for epsequation
Does anyone know , how to make discretisation for epsequation (in keps Turbulence Model) using FEM Standard Galerkin ?
Thanks for your help, Sigit 
Re: FEM discretisation for epsequation
If the k equation is :
Dk/Dt = P_k  e + div(nu+nu_t/sigma_k)grad k and the epilson equation is : De/Dt = c_e1 P_k  c_e2 e^2/k + div(nu+nu_t/sigma_e)grad e one can write the two equations in a similar form : for k : (D/Dt  div(nu+nu_t/sigma_k)grad + e/k ) k = P_k for e : (D/Dt  div(nu+nu_t/sigma_e)grad + c_e2 e/k ) e = c_e1 P_k e/k they can be discretize the same way using the weak formulation and the galerkin decomposition. Note that it is easier to considere the ration e/k constant by element in each term.
