I noticed that some star ccm+ users don't know how to monitor wave elevation time history at some certain place in the wave field. And there was one way to get an approximated data: create a point wave probe attached to the free surface and measure the position of that point, however, the result is not that good.( You can compare this method with the way I used.)

Let's first assume the positive Z axis in upward and positve X axis is along the wave propagating direction. Then you will need to:
1)create a plane section (derived part) normal to y axis, use the whole domain as the input.
2)select the plane section just created as the input and create a plane section normal to x axis, then you will get an intersection of the two plane sections which is a line (will be named plane section 2 if you have not create any other plane section before the 1 one)
3) create a line integral report, select the line as the part and choose volume of fraction>water in the field function.
4)create a monitor and plot for that report.

The result you will get is the wave elevation time history plus the water depth since it integraled the vof water along the line from the start point of the line to the end. So you can either create an expression report, call the line integral report and minus water depth or simply post prossess it via excel.

P.S: don't use the line probe build in star ccm+ to do so since the line probe built in has limitaion of integral I guess. (I've failed in doing so)
