Hello, Is it possible to add support for Ideas unv format and Plot3D p3d ? Thank you

nschloe commented 5 years ago

I've never heard of either of the formats. Please post links to the specifications.

Hello, For Plot3D:

From wikipedia: In computational fluid dynamics, the PLOT3D file format is a standard file format used for storing grid and results data. PLOT3D was created by NASA Ames Research Center in 1982 by Pieter Buning.
You can find the Plot3D user manual here . See Chapter 8 Data File Formats. p.162

For UNV I couldn't find much information, But:

It is supported in Salome SMESH module.
It is also available in GMSH.
There is a tool in OpenFOAM to convert Ideas unv format to OpenFOAM: ideasUnvToFoam.
It is also supported in Ansys Fluent. You can find more information about Fluent implementation of this format here.
Another page that gives more details about unv specification.

I found also another tool written in Fortran similar to your library that convert between different mesh formats including I-Deas Universal (.unv) : Feconv program.

All datasets wrt *.unv are available here. Just replace the corresponding number

Hello,

It would be very nice to have plot3d format available for CFD community. As far as I understood, @s1291 proposed some code but it was rejected because an ASCII mesh file was too big? If it's still open I can try to start from there and push something.

Please add .unv
