Dear all

I solve unsteady navier-stokes equation in FF++ and I want to store velocities (u,v) in a matrix for one period and for each time step. is there anyway to write it?

For instance,

for (i=0; i<T/dt; i++)

Solve Ns;

store each u and v in a column of matrix for each time and regenerate the matrix

end

at the end we need this, U=[[u,v]@t1,[u,v]@t2,…[u,v]@T]
