Default calculate the contour
Posts: n/a
I am using volume fraction fi to model the free surface.Now I have calculated volume fraction for every cell center, ie fi(x(i),y(i)).

Now I am using fi=0.5 for free surface.How can I use Fortran to find the location, that is, the x and y location when fi=0.5?

It can be drawn by somesoftware directly.But I need the data for outlet boundary condition to get hydrostatic pressure.

Any suggestions are welcome!Thank you!
