I've written a matlab program that reads the files created by sample. Sample creates those nice ascii column data files that are so convenient for matlab. Can I use sample to export a similar file for the entire vector field U? If not does anyone know how this could be achieved?

I think I found it already. It's a set type called 'array' but there are still some bits I don't get it.
Are e1 and e2 direction normals? Is origin the center of span box or the corner and then spanbox is opposite corner? And I'm pretty sure pointdensity is the number of samples in each direction. Code:
FoamFile { version 2.0; format ascii; class dictionary; location "system"; object sampleDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // interpolationScheme cellPoint; setFormat raw; sets ( sample { // Sample 'pointsDensity' points in a box with origin at 'origin' // plus the vector 'spanBox' type array; axis xyz; coordinateSystem { e1 (1 0 0); e2 (0 1 0); origin ( 0 0 0 ); } pointsDensity (10 10 10); spanBox (3 0.2 3); } ); fields ( U ); // ************************************************************************* // |
