[Nek5000-users] nek installation and running errors

Wed Jul 23 06:21:20 CDT 2014

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

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
