Hello, I am new to comsol and working on the capillary flow using Lamiar flow phase field method. Is it possible to calculate the average pressure at the meniscus exactly. Meniscus is an isosurface with constant volume fraction(0.5). I am able to construct a cut plane and get an average value of pressure along the cut plane. But meniscus is not a straight plane, so getting average pressure is difficult. Is it possible to use the meniscus surface as a cut plane and get the average value of pressure? Moreover if the meniscus is complex (due to geometrical constraints) the pressureis different at different points. So, is there any way to find pressure across the meniscus. Please find the meniscus shapes to get a better idea.
