[Nek5000-users] Error doing ./maketools for postnek

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

Hi all,

Thanks for the replies. I have tried with BIGMEM='true' but it still shows
me the same error. I think the two important parameters that I have to play
with is NELM in 'basics.inc' and MAXPTS in 'basicsp.inc'. Now I wanted to
ask,

Is there a constraint between these 2 parameters? It seems to me you cannot
increase one value as you want, without adjusting the other. Is there a
relation between them for successful compilation?

Previously I had NELM=100 000 and MAXPTS=20 000 000 and it seemed to work
and I didn't change these values, but lesser values might also work.

Thanks a lot,

Saikat
