Random initialization of P in 2D #32

Closed prkkumar closed 1 year ago

prkkumar commented 1 year ago

This PR implements a random initialization of Polarization for 2D problems. Prior to this we were initializing P using a deterministic approach.

Old way:

double tmp = (i%3 + k%4)/5.;
pOld_z(i,j,k) = (-1.0 + 2.0*tmp)*0.002;

New way:

pOld_z(i,j,k) = (-1.0 + 2.0*rng[i + k*n_cell[2]])*0.002;

where rng is a 2D array filled with uniform random numbers between 0 and 1.
