Exporting PDE toolbox solutions

I want to export PDE solution (potential over the plan) back to the MATLAB environment and be able to transform it to a solution on a rectangular grid (simple matrix - not the triangle nodes data). How can it be done?

After solving

1) Export from GUI the mesh (main menu - > Mesh-> Export mesh) ;

2) Export the solution (main menu - > Solve -> Export Solution);

3) define x,y -mesh e.g.:

x=-1:0.01:1;
y=-1:0.01:1;

4) convert to xy-grid and plot the solution:

uxy=tri2grid(p,t,u,x,y);
mesh(x,y,uxy)

Hey,

I also have a question. Is it possible that Matlab exports the boundary conditions autmatically? So that I dont have to do it manually?

With R2014b or later, you can interpolate the solution to a grid before exporting it.
