Now I want to solve the following system
Suppose the computational region is [0,1]^3 and the mesh Th. For the resulting numerical solutions, I would like to draw the magnetic field lines, velocity streamlines and vectors, and pressure contour plots at a given moment in the y=0.5 section. How should I proceed?
real h = 1./10;
mesh3 Th = cube(1/h, 1/h, 1/h);
solutions:
ux, uy, uz; p; Bx, By, Bz.
