Ok, I got it: you are talking about differencing schemes and not integration methods...However, still the higher time step sensitivity of the Euler scheme sounds strange to me...And, by the way, what...

Replies: 17 On the pimpleFoam solution algorithm Views: 16,796 Posted By vkrastev On the pimpleFoam solution algorithm Hi all, I'm trying to go deeper into the solution algorithm implemented in the pimpleFoam transient solver, especially for what concerns URANS incompressible applications. This is what I have...
