How large is your problem (number of elements and number of processors) ?

Hi Paul,

Yes I did do so. The compilation of the case goes fine. After that however, on running nek, instead of generating .dat file, it simply crashes. Note, the case itself runs just fine without the AMG solver, so I know that's not a problem.

Hi All,

I'm trying to set up the AMG solver in Nek5000 to solve for the pressures.
I tried following the instructions on Ch5 of the NekDoc available in
github, which contains instructions for running the AMG_Dump.

However, for some reason I'm unable to generate the *.dat files in my case
folder. I have uncommented the relevant lines in the makenek document and
tried it. However, it doesn't seem to be working.

Could anyone help out?

Sincerely,

Hi Amitvikram,

After you edited makenek, did you "makenek clean" followed by your standard makenek invocation?

That's important....

HTH,

Paul
