F. Re-Generating the Directivity Patterns File: TDIP2, TMONO

For active and/or radiating structures, in case the directivity patterns file (.PAT file) is accidentally deleted or corrupted, the user does not need to rerun the job. Because allvaluable data is saved in the .SY4 file, thisdirectivity patterns file can be recreated with the TDIP2 program (2D structures, extrapolation method) or TMONO program (when the fluid dampers stand in the far field).
