# freefoam-mergeOrSplitBaffles(1)

Detects faces that share points (baffles). Either merge them or duplicate the points.

## NAME

freefoam-mergeOrSplitBaffles - Detects faces that share points (baffles). Either merge them or duplicate the points.

## SYNOPSIS

**freefoam mergeOrSplitBaffles** \[-split\] \[-help\] \[-srcDoc\] \[-doc\] \[-overwrite\] \[-parallel\] \[-case *\<dir\>*\] \[-detectOnly\]

## DESCRIPTION

**TODO** write detailed description

## OPTIONS

- **-split**

  Split duplicate surfaces.

- **-overwrite**

  Overwrite existing data.

- **-detectOnly**

  Do no processing.

- **-case** *\<dir\>*

  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.

## NOTE

• can only handle pairwise boundary faces. So three faces using the same points is not handled (is illegal mesh anyway)

• there is no option to only split/merge some baffles.

• surfaces consisting of duplicate faces can be topologically split if the points on the interior of the surface cannot walk to all the cells that use them in one go.

• Parallel operation (where duplicate face is perpendicular to a coupled boundary) is supported but not really tested. (Note that coupled faces themselves are not seen as duplicate faces)
