Python Script Tutorial: Writing a JSon configuration file
As complexity increases one needs more and more flexibility in “configuring” a simulation. This is typically achieved by defining a "configuration file" which organizes all of the "user instructions" to be used in the configuration of the solver.
Some requirements for this configuration are:
- Must allow nesting of parameters (tree-like structure)
- Should allow using default values
- Must allow some form of type checking
- Should permit to echo all of the defaults in a single place
In order to meet such requirements Kratos introduces a "Parameters" object, which provides a thin wrapper to JSon strings.
The typical structure of a JSon file is like the following:
