contact diameter
 

Hi all,
I would like to plot the temporal evolution of the drop contact diameter upon impact on a surface using swak4foam or any other OF utilities. While Ploting it during free fall seems ok, during spreading is a bit trickier due to the substrate ( intersection between the substrate and the isosurface, alpha=0.5). Your help or hint will be appreciated...

Please take a step back and say to yourself: "If I wasn't working on this would I understand what the guy wants?" Especially the sentence "describing" the problem is a bit ... dense. It sounds a bit like "worked all day on it. Maybe someone on the Board can help. But I've got to leave in 1min if I want to catch the bus"
