Running casegeneration with a table (e.g. Moordyn line inputs) error with "AUTO" not found

[ogrootes]

When I running the case generation for Moordyn, I encountered the following error. With the MoorDyn v2, NType is not given separately. Based on line 511: NUMTAB_FROM_LAB_DIM_VAR += ['NTypes:AUTO','NConnects' ,'NLines:AUTO' , 'AUTO'], the tabDimVar will be split on the ':'.
The code searches for AUTO and this value is not found. The proposed fix ensures that the code search for the correct variable and not for AUTO

Can be replaced with the following code to prevent this error:

                else:
                    # We either use a variable name or "AUTO" to find the number of rows

                    for tabDimVar in tabDimVars:
                        d['tabDimVar'] = tabDimVar
                        if tabDimVar=='AUTO':
                            # Determine table dimension automatically
                            nTabLines = findNumberOfTableLines(lines[i+nHeaders:], break_chars=['---','!','#'])
                            # If split syntax was used (e.g. "NTypes:AUTO"),
                            # bind AUTO-detected size back to the variable before ':'.
                            if len(tabDimVars) > 1:
                                dimKey = primaryDimVar + labOffset
                                d['tabDimVar'] = primaryDimVar
                                iDim = self.getIDSafe(dimKey)

For this MoorDyn file, I also had to adjust the following inputs at line 509-514 in the fast_input_file.py:

        NUMTAB_FROM_LAB_DETECT   += ['Diam'       ,'Type'           ,'LineType'  ]
        NUMTAB_FROM_LAB_DIM_VAR  += ['NTypes:AUTO','NPoints:AUTO'    ,'NLines:AUTO']
        NUMTAB_FROM_LAB_VARNAME  += ['LineTypes'  ,'Points' ,'Lines'   ]
        NUMTAB_FROM_LAB_NHEADER  += [ 2           , 2               , 2             ]
        NUMTAB_FROM_LAB_NOFFSET  += [ 0           , 0               , 0                ]
        NUMTAB_FROM_LAB_TYPE     += ['mix'        ,'mix'            ,'mix'       ]

This solution is not ideal, as it it place's NTypes, NPoints or Nlines in the copied MoorDyn file
