The function [p e t]=importfilemesh(<name>) reads <name> and creates the corresponding matlab-pde formatted mesh (p, e, t) that can be handeled with the matlab pde toolbox.
The function u=importfiledata(<name>) reads <name> and creates the corresponding matlab node data (u) that can be handeled with the matlab pde toolbox.
The file "freefem_example.edp" generates two files :
- A freefem-formatted mesh : "Gilgamesh.mesh"
- A node data file : "Heat.bb"
The example file shows how to read the mesh and node data generated by "freefem_example.edp", and how to plot them.
Gilgamesh is a flash of genius
I just need to understand how it work in tree dimension envirenment.
After to save the freefem mesh I saved the vectorial solution:
file << "2 1 1 "<< u1.n << " 2 \n";
for (int j=0;j<u1.n ; j++)
file << u1[j] <<" "<< u2[j] << endl;
Now I need to plot velocity vectors as arrows with components (u,v) at the points (x,y).
could you give a example how to do that? Do you have any m-file? Thanks!
