Coordinate system for PSD excitation

      In a PSD analysis how to input excitation in a coordinate system other than global one?n

      One cannot directly apply PSD in a local coordinate system but can rotate the nodes in Modal analysis and align it with local coordinate system using 'Nodal Orientation' and then the PSD downstream will be applied to a local coordinate system. For more information please see the Ansys Help -> Mechanical Application 2020 R2 -> Mechanical User?s Guide -> Setting Up Boundary Conditions -> Types of Boundary Conditions -> Direct FE Type Boundary Conditions -> Nodal Orientationn
