Apparently I did not place the /bin in the executable path. now it works fine!
PATH=$PATH:~/.bin
export PATH
Thanks.

Thanks Paul. The issue is my system doesnt recognize the commands 'nek' and 'nekb' etc. Do I have to set the environment variables by sourcing the bash file?
Thanks.
Thangam.

Subject: [Nek5000-users] Extruding 2D .fld file to 3D
Hi Neks,
I followed what Fisher posted in the below link and tried to extrude a 2D flow into 3D.
http://lists.mcs.anl.gov/pipermail/nek5000-users/2013-October/002333.html
85 c-----------------------------------------------------------------------
86 subroutine usrdat2
87 include 'SIZE'
88 include 'TOTAL'
89
90
91 nelx=lelx,nely=lely,nelz=lelz
92 parameter (l2d=lx1*ly1*lelx)
93 common /mystuff/ u2d(l2d),v2d(l2d)
94
95 if (nid.eq.0) then
96 open(33,file='2D.dat')
97 do i=1,l2d
98 read(33,*) u2d(i),v2d(i)
99 enddo
100 close(33)
101 endif
102 nbytes = 8*l2d
103 call bcast(u2d,nbytes)
104 call bcast(v2d,nbytes)
105
106 call z_average_transpose(vx,u2d)
107 call z_average_transpose(vy,v2d)
108
109 call outpost(vx,vy,vz,pr,t,'3d.dat')
110 call exitti('Quit in usrdat2.$',nelgt)
111
112 return
113 end
114 c-----------------------------------------------------------------------
115 subroutine usrdat3
when I compiling the simulation ( with a 2D.rea and new SIZE) it displays errors,
nek5000/test/test3dimposed/3d/box.f:91.8:
nelx=lelx,nely=lely,nelz=lelz
1
Error: Unclassifiable statement at (1)
make: *** [nek5000] Error 1
Is there something I misunderstand ?
Thanks!
Wei

Hi,
I read in website that NEK5000 can't solve fully compressible flows.
How it changes density in low mach number flows (in which we have thermal
dilatation effects)?
Thanks

Subject: [Nek5000-users] nek installation and running errors
Hi all,
I am trying to download and install NEK5000 and trying to get a hang of it. I have downloaded and tried to the first example from the 'quick start' page. 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.
Number of processors: 1
REAL wdsize : 8
INTEGER wdsize : 4
No file SESSION.NAME; using defaults of
PATH=. and SESSION=NEK.
Beginning session:
./NEK.rea
timer accuracy: 0.0000000E+00 sec
read .rea file
At line 32 of file /home/thangam/nek5_svn/trunk/nek/connect2.f (unit = 9, file = '')
Fortran runtime error: File './NEK.rea' does not exist
I have put a copy of the scripts under the /bin directory as well.
I dont understand what I am missing and where im going wrong!
Thanks.
Thangam.

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.
Paul
