Application
|
|
foamToSurface
|
|
|
|
Description
|
|
Reads an OpenFOAM mesh and writes the boundaries in a surface format.
|
|
|
|
Usage
|
|
- foamToSurface [OPTION] \n
|
|
Reads an OpenFOAM mesh and writes the boundaries in a surface format.
|
|
|
|
@param -scale \<factor\>\n
|
|
Specify an alternative geometry scaling factor.
|
|
Eg, use @b 1000 to scale @em [m] to @em [mm].
