Hi,

I think it might be helpful to familiarize yourself with the Nek’s user guide first: http://nek5000.github.io/NekDoc/Nek_users.pdf Specifically chapter 2 which talks about setting up your path.

Using Visit might be a better option if you are just starting with Nek since there is a lot more documentation for it.

Let’s say you have result files for your case (let’s say a1) -  a10.f0000* or a10.fld0* formats. To visualize using Visit, type "visnek a1” which will generate a file a1.nek5000. Now you are ready to visualize.. open Visit (I have visit 2.9.1), and click “Open” and navigate to the folder where you ran your calculation. Once you are there double click on a1.nek5000. It should open fine and you can then use the options (open - pseudocolor - velocity) to visualize velocity results etc…

If you really want to use postx, type in postx to get started. This will pop up a black window. Depending on your display settings, the text at the bottom of the window might not be visible. If you don’t see any text, you will have to use the terminal to read the text (the text is duplicated there). I usually move the black window to the right side of the screen and terminal to the left side of the screen. Once you have done that, click on the black window and answer the question that you read on terminal window “Enter Session Name”. Type in a1 and hit enter. The postx window should populate with a plot of the mesh and a bunch of options on the right side which are self descriptive.

Thanks,
Ketan
