Plotting Free surface elevation

akuma · March 9, 2011, 07:04

Hi everyone,
I would like to plot the wave/free surface elevation at a given distance from the origin w.r.t time in star-ccm+ .
Also I would like to know how to get a scalar scene in which one plots the free surface elevation as the scalar field.
Any help in this regard will be appreciated.
Thanks.

Hi,

What do you mean you want to plot free surface elevation as a scalar field.

If you want to visualize a free surface you might want to consider using cell thresholds, refer help for the same.

If you want to visualize only the free surface only then you need to write a field function something like VolumeFractionWater>0 && VolumeFractionWater<0.5

Hi alastor,
Thanks for the advice.I meant making a scalar scene of position[Z] of iso surface.I think I got that.
I would like to know how to create a XY plot in which x axis is time and
y-axis is the wave elevation at a particular location(say at x=30m).
I created a point probe at a given location and gave its constituent part as iso surface.But when I use the point probe I get a clutter of points.
What I want is a result equivalent to a wave probe.
Thanks.
