[Nek5000-users] turbChannel compiling issue after adding more elements

Typically this is not needed. I guess you problem is related to some parameters in SIZE:

- set lelg to the total number of elements of your mesh
- set lpmin to a reasonable (small) value

Everything went very smooth (genbox and genmap both worked well) till the last step in “makenek” when it started to generate .ffile;  error occurred and it says:
