[Nek5000-users] Restart using a solution computed on different domain

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

You can use the generic fld reader to read the old field file data. This will interpolate all fields onto the new mesh. Not sure what you want to do with the part which is not covered by your old domain. For this area you have to provide somehow a meaningful IC.

Cheers

Hello,

  I have carried out a simulation for the flow past a cylinder at Re=100.
The extent of the domain in the is [Lx,Ly,Lz] = [30, 10, 10]; x is the
streamwise, y transverse and z is the spanwise direction. I have another
computational domain with size [50, 10, 10]. The mesh near the
cylinder in the two meshes is identical. If I use the fully developed 
solution
obtained using the first domain as a restart file for computation
using the second domain, will the first solution be projected on the 
second mesh
automatically by NEK?

Thanks.
N.
