Detailed description

Rfcon performs an initial run with a numerically given start solution for your problem. In order to use rfcon you need to prepare an equations file name.f and a constants file r.name as explained in Section 2, as well as the data file name.dat. The first column of the data file is time and the subsequent columns are the values of the state variables in the order U(1),...,U(NDIM). The data must be given for a full period of a periodic solution, or over a full time interval for boundary value problems. In either case, PAR(11) will be initialized with $\mathrm{PAR}(11) = t_{\mathrm{end}}-t_{\mathrm{begin}}$, where $t_{\mathrm{begin}}$ and $t_{\mathrm{end}}$ are the time values in the first and last row of your data file. Hence, it can be used for explicit rescaling of time. The initial parameters for your problem are defined as usual in the subroutine STPNT in the equations file.

Rfcon produces a run with name `dat' containing one solution with label 1 that can be used to initialize subsequent restarted runs. The constants file of this run will be a copy of the master constants file r.name. It is not possible to specify new values for AUTO constants on the command line.

Return values

Rfcon returns 0 on success and 1 if an error occurred or the -h switch was given. Note that a return with success does not mean that the conversion was successful. Rfcon does not verify that the numerical data is indeed a suitable start solution for your problem.
