October 17, 2014, 03:50	Using Shallow Water Equations	#1
Shabirmean New Member Shabir Mohamed Join Date: Jun 2014 Posts: 20 Rep Power: 12	I am trying to use the shallowWaterFoam Solver to extend it to a bigger area (more than 25 meters) to calculate height fields with varying boundary velocity. However whatever deltaT I set the program produces a floating point error after some time. When I reduce the deltaT, the the execution increases by a little number of loops and still crashes. This is because the velocity increases more than the amount I assume when calculating the Courant Number. WHat can I do?? Can someone please help?
