 To check that the radiative part of the physic has been requested, we will use a piece of code like (note that as radiative is a special case of adiabatic, we fist check that adiabatic physic is also requested):
 ```
   if (physic().adiabatic && physic().adiabatic->radiative) {
+    if (physic().adiabatic->radiative->opacityLaw == OL_CONSTANT) {
       ... do what need to be done  
     }
