- ffcx.main.get_parameters(priority_parameters: Optional[dict] = None) dict[source]
Return (a copy of) the merged parameter values for FFCX.
- Parameters
priority_parameters – take priority over all other parameter values (see notes)
- Returns
dict
- Return type
merged parameter values
Notes
This function sets the log level from the merged parameter values prior to returning.
The ffcx_parameters.json files are cached on the first call. Subsequent calls to this function use this cache.
Priority ordering of parameters from highest to lowest is:
priority_parameters (API and command line parameters)
$PWD/ffcx_parameters.json (local parameters)
$XDG_CONFIG_HOME/ffcx/ffcx_parameters.json (user parameters)
FFCX_DEFAULT_PARAMETERS in ffcx.parameters
XDG_CONFIG_HOME is ~/.config/ if the environment variable is not set.
Example ffcx_parameters.json file:
{ “assume_aligned”: 32, “epsilon”: 1e-7 }
