Default Eulerian Model
Posts: n/a
Hi Cadaei

I have another question about eulerian model. I ran my model with 0.005 time step size each with 70 iteration and I ran the same model with 0.001 time step size with same number of iteration per step and results were entirely different. Why is that? Total time to run is 0.65sec.

Keep reducing dt until solution doesn't change ... then you probably will have the right approximation. That's somehow like a 'grid' independence, but for the time variable.
