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
I am experiencing an issue where TUFLOW is producing different results when running the same model from (and writing output to): a) an external harddrive the internal hardrive (C drive) I performed a test running the exact same model from each the external harddrive and the C drive. The simulation carried out on the external harddrive ran through as normal where some flow broke out of the main channel. The simulation carried out on the C drive seems to go unstable at 1 hr 5 mins into the run when flow in the main channel stops flowing. Additionally the DV in the TLF drops rapidly at this point. The run does not officially go unstable and runs through the entire simulation time. I am unsure as to why this is occurring. I have heard of runs being run twice producing the different results, however in this case simulations that have been run from the external hardrive (and for that matter the C drive, even though flow stops flowing in the channel) are producing the same results when run twice. Any thoughts? Thanks Edward
