# Data from [P2,P2]

Hello,
I think I have something misunderstood about [P2,P2] fespaces
I have the following fespace that I use on an elasticity problem
`fespace Vh(th, [P2,P2]); Vh [ux, uy], [w, s]; `
To extract the displacement on the x axis I used
`for(int i=0; i < ux.n; i++){ ux1(i)=ux[](i); } `
By doing the same on to get the displacement on the y axis (uy) I get the same values as ux which definently doesnt make sense since I’ve only applied vertical force.
Do I understand something wrong about [P2,P2] spaces?

For a vector fespace `[ux, uy]`, the array `ux[]` is the array of all the degrees of freedom of the finite-element space `[P2,P2]`. The same is also true for ` uy[]`. So both `ux[](i)` and `uy[](i)` return the same `i`-th degree of freedom of the full fe-space…

To day to get only the ux replacement

``````     fespace Wh(th,P2); //scalar FE.
Wh wx,wy; // x,y déplacement
//  simple way
wx=ux;
wy=uy:

for(int i=0; i < wx.n; i++){ wx[][i]=ux[](2*i); }
for(int i=0; i < wy.n; i++){ wy[][i]=ux[](2*i+1); }
