Solve scalar transport equation along with Incompressible Navier Stokes
by Siddarth Chintamani 04 May '16

Hello all, I am trying to study scalar mixing from a jet. I can use the incompressible Navier Stokes solver to get the velocity at every time step. I am thinking of calling the advection-diffusion solver from the Navier Stokes solver every time step and solve for the scalar mixing. I was wondering if there is any other easier approach? Is there any example that I can look into? I greatly appreciate any help regarding this problem Thank you, Siddarth

Time dependent bodyforce
by Péter Tamás Nagy 03 May '16

Dear All, I have two questions in regard to the usage of the Nektar++ 4.2.0. 1. Is it possible to define time-dependent body-force for the Incompressible Navier-Stokes solver? Could anyone send me an example? 2. I read in the User Giude that the definition of the geometry can be stored in separate from the remaining configuration. It is not obvious for me how the solver will identify then the geometry or the configuration elements. In this case how should I call the IncNavierStokesSolver? Could anybody send me an example? I really appreciate any help. Best regards, Péter
