[Nek5000-users] Reminder Reg: Rayleigh Benard convection

Hi Vinaya,

You need to create a metafile with extension nek5000

http://nek5000.mcs.anl.gov/index.php/VISIT

which then you open in VisIt.

Also you can generate this file with the script

Best.

Dear Sir, 

Iam new to nek5000, so far I have ran certain example problems and a simple case where the box file is as follows: 


ddfree.rea 

2 

2 

Box 1 

-10 -8 

0.0 2.0 1. 

0.0 0.25 1.25 

P ,P ,SYM, , 

P ,P ,t , , 

Box 2 

-10 -10 

0.0 2.0 1. 

0.25 0.75 1. 

P ,P , , , 

P ,P , , , 

Box 3 

-10 -8 

0.0 2.0 1. 

0.75 1.0 0.8 

P ,P , ,SYM, 

P ,P , ,t , 



As a new nekuser I have used 8 processors for this problem,(as I dont know how to determine the correct number of processor) . I obtained .f files but these files didn't open in VISIT even when I changed it to .fld files. It was not able to read those files. 
I have observed that fld files directly obtained can be read by VISIT. Can you please tell me how do we get .fld and not .f files while running nek. 


I kindly request you to give a benchmark problem where Rayleigh Benard convection is applied. 
It will be of great help to me. 


with warm regards,
