laomashu 0 Report post Posted March 20, 2018 Hi, I have developed a rain on grid model and run it on a PC with GeForce GTX 780 Ti, driver version 372.90, the simulation was crash due to unstable. However the run was fine on other PC which has GeForce GTX Titan Black, driver version 372.90. I just wondering whether the graphic card has impact on the simulation.

Guest Stephen Kime Report post Posted March 21, 2018 Hi laomashu, The GPU device and to a further extent the hardware that you are running on, shouldn't impact the hydraulic results that are output and therefore stability of the model. However, the hardware may cause a model run to crash (not go unstable) due to hardware issues. Using different solution schemes however, such as Classic, HPC or GPU would almost certainly produce variations between runs and could result in one model remaining stable and the other one not. Could you please provide the TUFLOW Control File (*.tcf) and TUFLOW Log File (*.tlf) for both the successful and failed runs to support@tuflow.com for review?
