Hi all,

I want to insert a random source that changes at each step size so slice plot will be with respect to time like the source f(r,z,t0) will be the random 2d matrix generated at t0 and at t0+dt it will be the random matrix f(r,zt0+dt) and so on which will occur automatically and each slice will represent newly generated sources (Normal distributed where mean=0 and variance=1). I want to generate 2D matrix composed of random coefficients for r and z (Radial and Axial coordinates restricted by the cylinder dimensions) and at each time step it will generate new 2D Matrix until the end of the transient analysis (e.g. t=Tfinal). Is it possible to do that in COMSOL?

Regards,

Murat
