Sample smesh file: ``` # cube.smesh -- A 10x10x10 cube 8 3 1 0 0 0 2 0 10 0 3 10 10 0 4 10 0 0 5 0 0 10 6 0 10 10 7 10 10 10 8 10 0 10 6 1 # 1 for boundary info present 4 1 2 3 4 11 # region number 11 4 5 6 7 8 21 # region number 21 4 1 2 6 5 3 4 4 3 7 8 43 4 1 5 8 4 5 4 2 6 7 3 65 0 0 ``` NOTE: - for some reason boundary faces point inwards. I just reverse them always. Might use some geometric check instead. - marked faces might not actually be boundary faces of mesh. This is hopefully handled now by first constructing without boundaries and then reconstructing with boundary faces. ## OPTIONS *\* **TODO** Detailed description of argument. - **-noFaceFile** Ignore the face file. - **-case** *\* Case directory. - **-parallel** Run in parallel. - **-help** Display help message. - **-doc** Display Doxygen API documentation page for this application. - **-srcDoc** Display Doxygen source documentation page for this application. ## SEE ALSO An overview of FreeFOAM is given in [**freefoam**(1)](/freefoam/1.md). ## AUTHOR OpenCFD Ltd. ## FREEFOAM Part of the [**freefoam**(1)](/freefoam/1.md) suite. ## COPYRIGHT • Copyright © 2008-2012 Michael Wild. • Copyright © 1991-2010 OpenCFD Ltd.
