Hi All,
I'm looking for a software that could create a mesh and save it in a Plot3D format. I'm currently working on a project that uses a custom code to analyse the flow around an aerofoil, this code requires a multi-block, unformatted, double-precision plot3D file.
I have tried Ansys ICEM v170 but when I output the mesh I get a license error. I'm not sure if Pointwise is open source or not, but I assumed it is not, since I cannot find the download option. I have tried another software called Construct2D which outputs .p3d but the code rejected it.
can you please direct me to a software that could generate Plot3D files? I have tried .x format with the code and it worked but that file was created using a Fortran script that wasn't written by myself.


Thank you in advance.

Hi AeroSeeker,

I've gone down the Construct2D path before. I ended up writing my own program for converting the 2D ascii (if I remember correctly) to 3D double precision binary. If you don't find a better solution, it is available at github.com/hjabird/HBTK as a demo program (Plot3D_converter). It ought to compile under both MSVC and GCC (although you'll need a newer version), and you'll also need cmake. You'll need to set BUILD_DEMO_PROGRAMS to on (cmake -D BUILD_DEMO_PROGRAMS=ON ......) to compile it. The program should show its help at the slightest provocation.

Best wishes, HJAB

Thank you HJAB for the information, I shall compile it and I hope it works.

use tecplolt to convert other format to plot3d format.
