How to create a matrix of primitive variables or conservative variables

Thomas pan · January 20, 2016, 08:20

Dear Foamers,

I need to create a matrix of (rho rhoU rhoE) and the flux of them, which is the 5*3 matrix. How to create them use of code? I know the blockMatrix in extend, but I don't know how to implement.

After this, I also need to discrete them into the fvMatrix, can someone help me?

5*3 matrix？ I think it is just a vector which has 5 elements. You can have a look at densitybasedturbo package. In my viewpoint, the implicit temporal discretization is the reason why using fvblockmatrix. Otherwise, when using explicit temporal schemes such as Multistage Runge-Kutta may don't need blockmatrix.
