Wave generation in a 2D wave tank
 

When i plotted the surface elevation for waves generated against time , the values seem to be much bigger than the wave height :)I specified(i am using the linear wave theory). Hence even the plot seem to be cut off at peaks. Could anyone explain how to rectify this??

I am validating against a research paper and hence the dimensions of the tank needn't be the issue.


Also how can i set up a still water condition to record the 1 dof motion of a floater. Should i check the open channel condition then? I tried patching the air-water regions after initializing , but still am unable to get the two phases in the tank

Thanks in Advance:)
