DSADJ
Creates sensitivity of grid responses
DSADJ Creates sensitivity of grid responses
Creates sensitivity of grid responses with respect to design variables based on the
combination of adjoint and analysis solution matrices and element sensitivity data.
Applicable in frequency response or static analysis only.
