Cooling tower parameters definition

Activate the cooling tower module

As with other predefined physical models, the cooling tower module may be activated by setting the matching value in cs_glob_physical_model_flag, in the cs_user_model function (cs_user_parameters.c):

Define exchange zones

Cooling tower exchange zones and their parameters may be defined in the general cs_user_parameters function (cs_user_parameters.c).

The following code block shows an example of definition of a cooling tower exchange zone.
