Environment variables

Set the environment variable WRITE_FOAM_FILES to end the run at various locations in a NinjaFOAM simulation.

WRITE_FOAM_FILES = 0 generates the STL and writes the basic OpenFOAM case directory

WRITE_FOAM_FILES = 1 writes the mesh dict files (but does not generate the mesh)

WRITE_FOAM_FILES = 2 generates the mesh

Convert output

To convert OpenFOAM output to WindNinja output formats (.kmz and .asc):

../../output_converter/convert_output postProcessing/surfaces/951/U_triSurfaceSampling.raw ninja_output ../butte.tif

Set BUILD_CONVERT_OUTPUT = ON in CMake to build the output converter.

Sample the 3D output

Sample a surface

Generate a surface to sample with surfaceTransformPoints (see above). Then edit system/sampleDict if necessary and run sample -latestTime.

Sample a transect

Copy system/sampleDict_transect to system/sampleDict and edit $axis$, $xstart$, $ystart$, $zstart$, $xend$, $yend$, $zend$, and $nPoints$. Then run sample -latestTime.
