.SH "DESCRIPTION"
.PP
Given a \fBfield(2)\fP \fCfh\fP defined in a domain \fCLambda\fP, this function computes the level set defined by \fC{x in Lambda, fh(x) = 0}\fP\&. This level set is represented by the \fBgeo(2)\fP class\&.
.SH "OPTIONS"
.PP
The option class \fCleve_set_option\fP controls the slit of quadrilaterals into triangles for tridimensional intersected surface and also the zero machine precision, \fCepsilon\fP\&.
