how to monitor surface flatness
 

I am now using VOF model to compute free surface flow. I need to know when the surface will be even out. But how can the surface flatness be monitored? Anyone knows it! Thanks a lot.

Hi! Maybe you could read the z coordinate of all cells with a constant density value and then calculate the mean value and stndard deviation of it with use of custom field functions...

Hope it helps... mateus

Thanks. But how to read the z coordinate of all cells? Through UDF or other means?
