[Nek5000-users] Temperature Perturbation Zone

[nek5000-users at lists.mcs.anl.gov]

Hi,

I'm setting a 3D box to perform natural convection problems in a closed
cavity. After trying several method i can't manage to define a zone with a
variable temperature perturbation in the usrchk() routine.

Let's say, that temp = temp + A*sin(w*time) in a square of boundaries
[x_min, x_max] x [y_min, y_max] x [z_min, z_max] for x, y, z.

Any advice for implementing this?

Regards,
