PLOT3D files with Tecplot 2012
 
1 Attachment(s)
I am having problems reading solution files of PLOT3D format into Tecplot 2012. Here are two small test files I am using, one is the grid:

1
3 2 2
0.0 1.0 2.0 0.0 1.0 2.0 0.0 1.0 2.0 0.0 1.0 2.0
0.0 0.0 0.0 1.0 1.0 1.0 0.0 0.0 0.0 1.0 1.0 1.0
0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0

and the other one is the solution:

1
3 2 2
0.0 1.0 2.0 0.0 1.0 2.0 0.0 1.0 2.0 0.0 1.0 2.0

The domain is basically one block of size 3x2x2 and the files are ASCII formatted. I can read the grid file into Tecplot (see attached image) but when I try to read to solution file I get the following error:

File "sol.xyz" is not a solution file.

I was able to read PLOT3D files into Tecplot 2008, so I am very puzzled why I can't read them into Tecplot 2012. Is there something wrong with the solution file itself or a problem with Tecplot 2012.

Thank you,

Nikos

When I add an extra line to solution file containing values for the Mach number, angle of attack, Reynolds number and time:

1
3 2 2
1.0 0.0 100.0 0.0
0.0 1.0 2.0 0.0 1.0 2.0 0.0 1.0 2.0 0.0 1.0 2.0

I don't get the previous error message but when it tries to load the file Tecplot crashes.

In previous versions of Tecplot we read function and solution files in the same place. Now we have split this into 2 distinct categories for function and for solution. If you open your file in the function section (instead of solution) it will work.


What you are calling a solution file is actually a function file. A solution file always has the variables, RHO, RHO-U, RHO-V, RHO-W, and E.
