Hi Neks,

When I used genmap to generate a .ma2 file, this message was shown:

jhe@heft-vis2:~/Nek5000/run/FreeInjection_AirHe_Gmsh_Test$ genmap

Input .rea / .re2 name:

fi

reading fi.re2

Input mesh tolerance (default 0.2):

NOTE: smaller is better, but generous is more forgiving for bad meshes.

using default value

reading mesh data ...

Abort: number of elements too large 311860

change MAXNEL and recompile

exit status 1

It looks like the number of element exceeds the limitation, how should I change this limitation? Thanks!

Regards!

Hi Jundi,

You can change the MAXNEL inside

Nek5000/tools/maketools

You will need to recompile the genmap with a clean first

I usually do `cd genmap && make clean` instead of using ./maketools clean to only make clean the genmap.

Hopre this helps,
