Hi Alex,

some hints:
– choose larger git sizes, smaller dx
– uMax should stay below 0.12, if choose smaler time step sizes or set smaller uMax (depending on the used unit converter)
– check the source of unstability (stop simulation if uMax>0.3 for the first time in the main loop and write results, output the velocity and locate where the great values orrur.
