How to use Forward Euler in OpenFOAM 3.0.1
All the time schemes in OpenFOAM 3.0.1 are implicit:

The off-centering parameter for the CrankNicolson scheme cannot be set such that the scheme reduces to Forward Euler. Is there a quick way to use an explicit time scheme? I am, specifically, interested in Forward/Explicit Euler.

Yes, use fvc not fvm for space discretization. It will create diagonal matrix for linear solver which corresponds to explicit time discretization.

All times are GMT -4. The time now is 10:58.
