How does one set an inital water level for a tank
 

I am trying to speed up my convergence time for a SS tank problem and I was running. I have not had it work yet but I am pretty sure I will have a non zero water level in the tank. I wanted to start with one but I am not sure how I input this.

thanks in advance.

I am not sure what you are asking. Are you asking how do you set up an initial condition for a free surface simulation? The CXF tutorials has an example of how to do this - free surface flow over a bump.
