As in \S\ref{extract}, the option \inltt{bnd} specifies which boundary region to extract. Note this is different to MeshConvert where the parameter \inltt{surf} is specified and corresponds to composites rather boundaries. If \inltt{bnd} is not provided, all boundaries are extracted to different fields. To process this file you will need an xml file of the same region.

The input \inltt{.fld} files are the outputs of the \textit{wss} module. If they do not contain the surface normals (an optional output of the \textit{wss} modle), then the \textit{shear} module will not compute the last metric, |WSSG|.

Note this is different to MeshConvert where the parameter \inltt{surf} is specified and corresponds to composites rather boundaries. If \inltt{bnd} is not provided, all boundaries are extracted to different fields. The \inltt{addnormals} is an optional command argument which, when turned on, outputs the normal vector of the extracted boundary region as well as the shear stress vector and magnitude. This option is off by default. To process the output file(s) you will need an xml file of the same region.
