This is where postprocessing information will appear.

Surfaces with eFEMpart

Lines are implemented with the mySurface datatype, which can be initialized by

surf = mySurface([x0,y0],[x1,y1])

where the line surf is defined between the two points (x0,y0) and (x1,y1)

Inteprolation

To interpolate a scalar field u, defined on a finite element mesh mesh, to a point p, use the following function:

pointTransform(mesh,u,p)

To compute the velocity flux along a surface

VelocityFlux(mesh,u,v,surf,N)
