THe only other option I can think of is to define monitor points and manually get the max/min values of them. This...

You would have to have these regions present in the mesh but they don't need to be boundaries, just mesh regions is...

If this is what you are looking for then why didn't you say so at the start? You cannot generate line objects in the solver to my knowledge....

What you describe sounds easy - draw a line where you want to calculate it and use the function calculator on that line to get the maximum Air.Velocity and maximum Water.Velocity. Doesn't that do...

OK, but as the variable you talk about is fundamental to a inhomogeneous model it will be in there somewhere, it is just a matter of finding its name. Look in the CEL reference guide in the...
