mpycopy

This tools copies a given case setup to a new location. Simple case setups are copied without modification. Templated case setups, i.e. setups that feature

• a top-level caseParameterTable.ecsv file in the Astropy ECSV format that lists all case variations with the corresponding parameters

• one or more files with the ending .jinja containing placeholders for these parameters

are rendered into a ready-to-run state using the Jinja templating engine.

Usage

mpycopy input output [options]

where input is the (templated) case to be copied to the output directory.

Examples

Render a Single Case from Template

Render a specific case from a templated setup:

mpycopy --case case1 ./template ./run/case1

Render All Cases from Template

Render all cases defined in the parameter table:

mpycopy ./template ./run

This will create subdirectories in ./run for each case defined in caseParameterTable.ecsv.

Template Structure

A templated case should contain:

caseParameterTable.ecsv - Table with case parameters:

case velocity temperature
---- -------- -----------
low  0.5      300
high 1.0      350

caseParameterDict.jinja - Jinja2 template file:

velocity {{ velocity }};
temperature {{ temperature }};

After rendering, the template file caseParameterDict.jinja becomes caseParameterDict with values filled in:

velocity 0.5;
temperature 300;
