Hello,
I am to post process output generated in plot3d format produced by a opensource solver called ISAAC( integrated solution algorithm for arbitrary cases). I have two ascii formatted files
1. '*.g.fmt' ---> called grid file
2. '*.q.fmt' ---> called solution file

I tried using a free to use postprocessor called MayaVi. It asks for xyz file and q file. I have 'q' file whereas I suspected the xyz file would be the grid file. I tried giving the 'g.fmt' file in place of xyz file. It doesnt open. I googled for xyz file format and couldnt get it.
1. If any one can help me in telling the format of xyz file format, it would be of
great help.
2. Is grid file and xyz file one and the same?
3. Anyone here have experience using ISAAC?

Please reply

Hi
I have used ISAAC. Mayavi support for plot3d is rather basic. You can try cgx from Calculix

http://www.calculix.de/

which can read these plot3d files. Or you can convert them to some other format. I have written a program to convert to vtk format, see

http://svn.berlios.de/viewcvs/nuwtun/trunk/src-utl/

There is one program to convert 2d files and one for 3d files. They work only for single block plot3d files. But you can easily modify them for multiblock.

VTK files can be seen using the free and excellent software paraview http://www.paraview.org

Dear Praveen,
I tried running plot2vtk_2d.f in Microsoft visual fortran in a 32 bit XP platform,
It says the 'Specify one argument' and then exits. It doesn't ask for any file name or anything.Kindly tell me how to go about this?

Regards,
Kishore

ISAAC gives you output files like

naca.g.fmt
naca.q.fmt
etc.

You run

plot2vtk_2d naca

to create vtk file naca.vtk which can be viewed in paraview or visit.
