Hi Jian,

Assuming your mesh is centered around x = 0, y = 0; you can put the following code in the usrdat2 routine in your usr file:

do i=1,lx1*ly1*lz1*lelt
   xm1(i,1,1,1) = 4.*xm1(i,1,1,1)
   ym1(i,1,1,1) = 4.*ym1(i,1,1,1)
enddo

When you run your case, the spectral element points in each element gets mapped to a location that is 4x farther away from the origin.

Sincerely,
Kento
