Hello, dear participants. I solve the problem of elasticity in 2D using varf. I get the solution as a vector [u1,u2]. Is it possible to get directly the arrays u1 and u2 separately using some command in FreeFem++?

Look at the manual or search on the forum, e.g., [A small puzzle about the length of vector valued fespace](https://community.freefem.org/t/a-small-puzzle-about-the-length-of-vector-valued-fespace/2610)

The simple way is just to copy your solution u1 u2 in an other fe function w1 and w2

Where  
fespace Wh(Th,P2);  
Wh w2=u1,w2=u2;

Now w1 is the vector with only u1 composante.
