Hi Himanshu,

Make sure that your parameter(23)=3 in .rea which is your number of passive scalars or NPSCAL.  If this does not help, can you tar up your .fld & .rea file and email me it offline (obabko at mcs.anl.gov) or send me the link to it on the web?

Best,
Aleks

Hi Aleks, 


I made the changes you suggested and re-compiled postx. But, the passive scalar option still does not show up when I do "set plot format". Please let me know if i missed anything or I need to do something differently? 
Thank you, 
Himanshu

Hi Himanshu, 

Sorry, I forgot the name of the file:

Hi Aleks, 


Thank you for the suggestion. In the postnek directory there are many .f files, do you know which one has the MAXFLD parameter? 


Thanks, 
Himanshu

Hi Himanshu, 

Try to increase MAXFLD parameter in nek5_svn/trunk/tools/postnek (i.e., maximum total number of fields in .fld file) and recompile clean. 

Best, 
Aleks

Hello neks, 

I am trying to use postx to read some fld files that have passive scalar 
information. There are 3 passive scalars. The passive scalar options appear 
when I do "Set Quantity". But, when I try to set the plot format and read 
the input file, the passive scalar option is not shown in the Nekton menu. 
The velocity, co-ordinates, temperature options are present. Any idea why 
the passive scalar option does not appear? 

Thank you, 
Himanshu

Hello Neks, 

I am trying to post process the fld files using postx to generate a uniform 
xy grid of passive scalar data. During post processing the top half of the 
circular cross-section is cut-off (its a cylindrical domain with aspect 
ratio of 10 i.e radius to depth). The output file generated has only zeros 
in it. I have checked the input file and it has information of the entire 
domain. Any idea if i need to do something differently. 

Thanks, 
Himanshu
