# surfaceBooleanFeatures(1)

part of OpenFOAM (The Open Source CFD Toolbox).

## NAME

surfaceBooleanFeatures - part of **OpenFOAM** (The Open Source CFD Toolbox).

## SYNOPSIS

**surfaceBooleanFeatures** \[*OPTIONS*\] *action* *surface1* *surface2*

## DESCRIPTION

```
Generates the extendedFeatureEdgeMesh for the interface created by a boolean
operation on two surfaces.
```

## ARGUMENTS

- *action*

  One of (intersection \| union \| difference)

- *surface1*

  The input surface file 1

- *surface2*

  The input surface file 2

## OPTIONS

- **-case** *dir*

  Specify case directory to use (instead of the cwd)

- **-invertedSpace**

  Do the surfaces have inverted space orientation, i.e. a point at infinity is considered inside. This is only sensible for union and intersection.

- **-perturb**

  Perturb surface points to escape degenerate intersections

- **-scale** *factor*

  Geometry scaling factor (both surfaces)

- **-surf1Baffle**

  Mark surface 1 as a baffle

- **-surf2Baffle**

  Mark surface 2 as a baffle

- **-trim** *((surface1 volumeType) .. (surfaceN volumeType))*

  Trim resulting intersection with additional surfaces; volumeType is 'inside' (keep (parts of) edges that are inside), 'outside' (keep (parts of) edges that are outside) or 'mixed' (keep all)

### ADVANCED OPTIONS

- **-debug-switch** *name=val*

  Specify the value of a registered debug switch. Default is 1 if the value is omitted. (Can be used multiple times)

- **-fileHandler** *handler*

  Override the file handler type

- **-info-switch** *name=val*

  Specify the value of a registered info switch. Default is 1 if the value is omitted. (Can be used multiple times)

- **-lib** *name*

  Additional library or library list to load (can be used multiple times)

- **-noFunctionObjects**

  Do not execute function objects

- **-opt-switch** *name=val*

  Specify the value of a registered optimisation switch (int/bool). Default is 1 if the value is omitted. (Can be used multiple times)

- **-doc-source**
