[Nek5000-users] nek installation and running errors

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

You should use one of the scripts in

    trunk/tools/scripts

The usual command would be

nek blah

where blah is the name of your .rea file.

To run in background (strongly recommended),

nekb blah

For mpi there are nekmpi and nekbmpi

nekmpi blah 4

would run on 4 ranks, etc.

There is some description of this in the manual.

The compilation is successful after the makenek command. However, it does not realize further nek commands such as nek, nekb etc. (command not found error)I went on to issue the command ./nek5000 eddy_uv and following was the output.
