Optional parameters

DESIGN VARIABLE: Include this parameter to specify a spatial distribution of design variables in an adjoint design sensitivity analysis.
INPUT: Set this parameter equal to the name of the alternate input file containing the data lines for this option. See Input Syntax Rules for the syntax of such file names. If this parameter is omitted, it is assumed that the data follow the keyword line.
