Description |
defining the data to be stored at a reference time |
Usage |
Reference_set_data NUM=ival where ival is the data structure number |
Description |
Overview Reference_set_data allows the state for the specified variables at a particular time to be stored and maintained throughout the solution. Both this state data and the difference between the current state and the reference state can be output to the plot file for visualisation. This can be useful, for example, in viewing the change in state from geostatic initialisation to the end of the simulation, or from before and after a kinematic event (e.g. change in porosity during a shortening event).
Notes •The reference state is taken when the Reference_set_data is encountered; e.g. if the state after geostatic initialisation is required the data should be specified after the geostatic stage. •More than one Reference_set_data may be defined.

Flag denoting to create a new set after deposition of each new stratigraphy unit.

If Deposition_flag is set to 1 or 2 than a new reference set is created after deposition of each new stratigraphy unit.

Valid values are: • 0 - Keep previous reference set (Default if Deposition_flag = 1) • 1 - Delete previous reference set (Default if Deposition_flag = 0)
