[Nek5000-users] NEKTON and Gambit

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

Hi, 

Yes I am out of the country at the moment but can pass along the code when I get back (in a week). 

And yes Gambit has an export format for Nekton but I couldn ´t make sense of it. I used a portion of matlab code Paul had written awhile back that writes the REA format, the rest of the code simply extracts information from the Generic Mesh file (Neutral file . neu ) exported from Gambit and prepares it to write the REA. 

I´ll post the code when I return and try to include some explanation of how to get started with it. I included lots of comments so it should be straight forward. 

Until then, 
Michael M

Hi Josh, 

Yes, I recall that. For sure, I'd be grateful if you could let him know 
that he has an eager customer for his program. 

Cheers, 
Frank
