Does GetEFDC work with EFDC version 8.2? If not, do you have a compiled version for 8.2? For my version 8.2 model, GetEFDC crashed during the step “READING EFDC.INP”. The error read “EFDC.INP: Error Reading 23”. Looking at the source code, it seems to be expecting another two variables in card 23: NQCTLSER & NQCRULES. Possibly these were added after version 8.2? Are they necessary for GetEFDC?
