  1. Dear Admin/ Members, I ran an exact same setup with GPU and CPU solver (“2 hours” flooding event, Rain on grid, Watre level BC). Surprisingly the water levels (extracted from PO lines) in GPU are constant over the 2 hours event and are different from what CPU solver returns! Differences are between 1.2m to 2m! Any comment or suggestion is highly appreciated. Cheers, Ali
  2. Hi admins, Have just been running a ~ 50ha ROG model, pure 2D domain with the GPU solver. We really wanted to run it using 1m cells so we could pick up on small overland flow paths within the site. the model continued to be unstable until we adopted 4m cells. The 4 hour simulation ran very very fast, in about 5 minutes. Am I right in thinking that maybe the time step may have some impact on the instability? Are there any codes that can applied to slow the time step and accept (force) a smaller grid, such as a 1m or even 2m? Cheers
