The forward simulation generated data files are discussed in this manual page. Note that despite most of the data being automatically generated, the main data file may require some edits (e.g. assignment of geostatic data set for deposited units in order to deposit following the NCT (Normal Compaction Trend) rather than at the reference porosity).
Generated Rest_002_Step3 data file
Here the generated data for the forward model datafile is discussed. Note that data to be included (contact, adaptivity, geostatic, etc) specified in the forward create data file is not discussed here as it is detailed in Step 2 Forward create data file page.
