It must be preceded by one or more *SENSITIVITY steps and the design variables must be of type coordinate. The sensitivities calculated in the sensitivity steps can be used as an objective or as constraints. The feasible direction step calculates the resulting constrained sensitivity. There are no parameters for this keyword.  <P><P> <BR>  <P> First line:  <UL> <LI>*FEASIBLE DIRECTION </LI> </UL>  <P> <PRE>
