# freefoam-splitCells(1)

Utility to split cells with flat faces.

## NAME

freefoam-splitCells - Utility to split cells with flat faces.

## SYNOPSIS

**freefoam splitCells** *\<edge angle \[0..360\]\>* \[-geometry\] \[-tol *\<tolerance\>*\] \[-srcDoc\] \[-doc\] \[-overwrite\] \[-help\] \[-set *\<cellSet name\>*\] \[-case *\<dir\>*\]

## DESCRIPTION

Uses a geometric cut with a plane dividing the edge angle into two so might produce funny cells. For hexes it will use by default a cut from edge onto opposite edge (i.e. purely topological).

Options: - split cells from cellSet only - use geometric cut for hexes as well

The angle is the angle between two faces sharing an edge as seen from inside each cell. So a cube will have all angles 90. If you want to split cells with cell centre outside use e.g. angle 200

## OPTIONS

*\<edge angle \[0..360\]\>*
