Hello all,
I'm new in Openfoam.
How to convert a .p2d file for a foam format?

[adoledin]

I don't know how to make file conversion.
I'm trying to import NASA grid in OpenFOAM... but I don't know how to!
The file format is .p2dfmt. How to convert for a foam format?

Hi,
Try this in a terminal:
plot3dToFoam -help

Best regards,
Paulo

Thanks Paulo!
I have to use plot3dToFoam -2D <thickness> <filename.p2dfmt>
But I have a problem.

Can you help me?

Hi Mateus,
The application plot3dToFoam work with files in the ASCII format, but it found something in line 2466 that cannot be interpreted as an ASCII character. I suggest that you try to open the file with an editor and try to figure out what happened in this line.
Best Regards,
Paulo

Hi Mateus,
Try to see if there is anything strange in line 84030 of the input file.
