[Nek5000-users] Using postx

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

Hi Rich,

Please, read the header of the file eddy_uv.usr

In this file geometry is remapped to 0 to 2 pi in usrdat2()

Let me know if you have other questions.
Aleks

Okay, I made the header and got VisIt to read in a file. However, the spatial coordinates shown in VisIt are not correct. From the example menu, I use eddy_uv, a 2D problem that is defined on boundaries [0,1] for x and [0,1] for y. You can see this in the .box file and the .rea file. However, VisIt shows the domain as from [0,6.3] for both x and y, see attached figure. What is going on here?

Hi Rich, 

You have to make a short header file that VisIt then opens. 

Aleks Obabko set up a how-to here:

Aleks is gone, but I can help if you run into trouble. Just email me personally and we can get it figured out ( hchilds at lbl.gov ). 

Best, 
Hank

Okay, so how do I use VisIt. I have version 2.4.0 on my PC. But it won't read any of the files from nek5000. Do I need to set some switch to enable a visit file?

Hi Rich, 

Sorry about this. 

It turns out that most folks have been using VisIt for 
their analysis, so the incompatibility between postx 
and recent updates to file formats have generally not 
been an issue. 

I see from Katie's email that she's already working on 
an update to postx.
