P3D File Format
 

Hello wonderful people,

I am working on flat plate boundary layer analysis. For that I have created coordinates in C++ and written in P3D file format. I am using GASPex software from aerosoft which requires P3D format for grid import.

In file I have written number of zones in first line. Then following lines have resolution for each zone. And then I am listing coordinates with breaks for changing from x-coordinates to y-coordinates and vice-versa.

I am getting error in reading the P3D file in software. Does anyone know how this file format works?

I need detailed description so that I can identify my mistake!

Thank you.

Assuming that you mean plot3d when you say P3D, I would look here -

Also be aware that plot3d comes in FORTRAN formatted and unformatted flavors.
