ddt schemes for virtual time
I want to solve an equation in a virtual time Tau inside the classic time looping.
I wanted to implement it using a kind of fvm::ddtau, in order to test different schemes, is it possible?
I tried to stock the external deltat, change the deltat for the virtual time loop, and in this way to use fvm:: ddt. But the results was very bad and create confusion obviously I can easily understand why.
Could someone give me informations about the best way to do that?
