Hi All,In fact I do not know exactly if this is a question for GetDP or for Gmsh ...
Assume that using GetDP, I have solved Laplace equation in a 2D domain with or without holes and that I plot isocontours of the scalar potential using Gmsh. I would like to be able to retrieve arrays containing the (x, y)- coordinates of the points making these isocontours, but I don't know how to get these arrays variables or export the coordinates in ascii files. In 2D, Gmsh is able to plot a given number of iso-value contours of a scalar field, thus there should be a way to get these coordinates.
A similar but more complicated problem arises in 3D. In this case, I would like to obtain arrays of (x, y, z)-coordinates along the lines corresponding to the intersection of isopotential surfaces with the different domains surfaces (planar or curved and with or without holes).
Any help is more than welcome.
