I have been trying to study the flow around a water body in a water tank for weeks and after overcoming errors in different phases of setting up a simulation. Earlier I had a CFL issue very early into the simulation, at present the simulation runs for about 2 secs of physical time and crashes by throwing up either a “Fatal I/O Error” or “CFL exceeds 1” error. I am very close to giving up in running my project on simscale altogether Here is a link to my project - https://www.simscale.com/workbench/?pid=4808040960984650438#tab_0-0. Really would appreciate some help. Thanks !
