Thank you very much, Alex, for such a fast reply! I will certainly try what you suggested. I'll keep you posted. Best, Rakesh On Sat, Jul 16, 2011 at 7:47 PM, <[email protected]> wrote:

Hi Rakesh,

For the 3D MHD example please look for the case

nek5_svn/examples/mhd/gpf.*

and check the comments in gpf.usr for the details.

An upgrade of the code which handles magnetic boundary conditions that are different from velocity BCs has been successfully tested for a magnetoconvection case and I will try to finish the corresponding example with the write-up in one month.

In the meantime for your setup you can use the boundary condition string

'ddn'

in .box or in .rea file with mesh (no .re2 i.e. NDIM>0 in .rea) for the case of the idealized isolator in Bz field:

Bx = By = 0 = d Bz / dz

Please, test this for your setup first and let me know if you encounter any problems. Best, Aleks

Dear Nek developers,

Kindly provide an update on 3D MHD example for Nek5000? I read in a year old thread that Aleks was working on that.

Eagerly waiting for the example.

Cheers, Rakesh _______________________________________________ Nek5000-users mailing list [email protected] https://lists.mcs.anl.gov/mailman/listinfo/nek5000-users _______________________________________________ Nek5000-users mailing list [email protected] https://lists.mcs.anl.gov/mailman/listinfo/nek5000-users
