Hi All,
Can someone please suggest how to define an initial liquid level for a vof model? In Fluent, there is a function 'patch' to do this. I am not sure if CFX also has a similar tool. Thanks, Gab |

You can use a step function with a coordinate. For everything above x=0 to be gas use:
VfGasIni=0.999*step[x/1[m]] VfLiquidIni=1-VfGas Remember to provide a decent pressure distribution as well. This is very well documented in the help. Please read it good. Another good advice is to use a minimum fraction of 1e-5. Do not use 0 as this will lead to problems..... Gert-Jan www.bunova.nl |
