Input / Output

 

In this section the reference pages for reading (input) and output of data are documented. The data structures concerning input of data documented here are:

 

Include: used to include external files into the main data file. This allows to split the data file definition into several sub-files.

 

Restart_read_data: Used to read restart (.rst) files previously output from ParaGeo simulations

 

 

The different data types that can be output during an analysis are:

 

Plot files: variables are output in plot files which can be visualised in ParaView. By default all variables relevant to the models deployed in the analysis are output. Nonetheless the Output_data structure can be used to specify which variables are output (and thus which are not output). This can be useful to turn off output of non-desired variables in large simulations which may require a lot of memory space.

 

History output: evolution of variables as a function of time. History output can be performed at:

oGlobal: History output of global energy and convergence variables (History_global)

oPoint: History output at Lagrangian points (History_point)

oSurface: History output at a surface (e.g. a fault). Output of variable data can be averaged across the surface and also it can be performed at every point of the surface (History_surface).

oLine: History output along a line which can follow a non-lineal path (e.g. a wellbore path). (History_sect_line).

 

Material Grids: Grid independent to the FE mesh which is useful to visualize deformation patterns.

 

Restart data: data used to restart the simulation at a restart point. Output of this data is specified in Control_data.

 

Reference set data: State of specified variables at a given time can be stored as a reference state. Then the difference between the current state and the reference state can be output.

 

 

 

Examples

 

All tutorial examples demonstrate output of data of some type (mainly plot files and history data). Tutorial examples demonstrating a specific type of data output are:
