Hello, I am doing a 3D simulation having Nx,Ny,and Nz of 88,88, and 72 grid points. I use Nt(time grid) of 1017. I was recording u_max and u_nonstaggered using kspaceFirstOrder3D. However, I am getting U_max result in 88*88*72 format and u_nonstaggered as 3*1017 format. What does it refer actually by 3*dt size in result?
If I need to plot output parameter (say U_max) at 3 different instatnts (say 5, 10, and 15 miliseconds), how can I do that?
