 * __CFD_CONFIG_FILE_NAME__ (string): Path to the fluid cfg file
 
-* __CSD_SOLVER__ (string): Behaviour of the structural solver to be used. AEROELASTIC if the structural equation of motions must be solved, IMPOSED if a movement of the structure is imposed
-                     
+* __CSD_SOLVER__ (string): Structural solver to be used. As of now, only the native modal solver is used, activated with the keyword NATIVE. However, other solvers can easily be added
+     
+* __IMPOSED_MOTION__ (string): YES or NO. Specifies wether the structural solver will integrate the structural equations or just impose a specific movement. In the latter case, forces are not mapped onto the structure, as it would not be required.
+
+* __MAPPING_MODES__ (string): YES or NO. Special feature that can only be used with the native solver. Used to extract the mapped modes onto the aerodynamic mesh.

 * __CSD_CONFIG_FILE_NAME__ (string): Path to the solid cfg file
 
 * __RESTART_SOL__ (string): YES or NO
