Test cases
The main objectives of the test cases are to:
- check the installation of the model code by the user;
- perform simulations without any programming effort by the user;
- demonstrate the various options, available in the program (e.g. selection of a particular scheme by setting the appropriate switches) and, in particular, to show how model results are affected by different choices of model switches or parameters;
- test the portability of the program;
- provide a debugging tool for further developments of the model code.
More information about the test cases is available in the COHERENS manual.
