t := zone.stress(p)
zone.stress(p) := t

Get/set the zone stress. Get: The zone-averaged value of all the internal tetra is returned, weighted by volume. Set: All of the zone’s internal tetra are assigned the same stress value. Note that compressive stresses are negative in FLAC3D.

Returns:t - zone stress tensor or value
Accepts:t - zone stress tensor or value
Arguments:p - zone pointer
