Detailed Description

Manages the coupling analysis with thermal hydraulics code COBRA-EN.

This Object creates the input file of the thermal hydraulic code COBRA-EN. It manages the running and the update of the new temperature and densities into the simulated reactor. This class do not directly creates the geometry. It call class ReactorMesh to generate a filled geometry (for use : cf. class ReactorMesh). So about the geometry and neutronics aspects you have to use methods of the ReactorMesh class.

Data are in SI (ex : dimensions in meters, power in watts,...)
