UGVADD<br />

Adds two displacement vectors when direct addition based on small angle theory<br />

would yield erroneous results. For old geometric nonlinear analysis only.<br />

Remarks:<br />

1. SIL may not be purged.<br />

Adds two displacement vectors when direct addition would yield<br />

erroneous results<br />

UGVADD UGNI,DUGNI,SIL/<br />

UGNT $<br />

UGNI Displacement matrix at converged step in the g-set.<br />

DUGNI Incremental displacement matrix between the last two converged steps.<br />

SIL Scalar index list.<br />

UGNT Total displacement matrix in the g-set.<br />

2. If either UGNI or DUGNI is null, the addition will be done directly.<br />

3. UGVADD is used only in SOL 4.
