Find Referenced Variables - Model Explorer

I am looking in Model Explorer at a block in a MATLAB model (power_fuel_cell.mdl) and at the parameters. The first is "Resistance Ron" which has the variable "FC.Rohm" in it. I want to find where this variable is defined (and a few otehr vaiables which i cant find). If i right-clock on the diode model and select "Find Referenced Variables", i get no results found.... are there some variables defined somewhere in an .m file that initialise when the simulink model is run? How do i find where they are?

Thanks

FC is calculated in the mask initialization based on the parameters you enter in the mask: right-click on the fuel cell block, select "View Mask" and go to the "Initialization tab". You'll see the following code:

block = gcb;
%%DO NOT CHANGE THIS ORDER
FuelCellCback(block,'Update')
[FC, WantBlockChoice, Ts] = FuelCellInit(block);
powericon('SetInternalModels','set',block,WantBlockChoice);
FuelCellCback(block,'')

Thankyou for your reply, is there any way to see how the mask parameters are used in the initialisation of FC.Rohm and other model variables? Or would their initialisation be in an encrypted ".p" file?

The FuelCellInit function is p coded:

>> which -all FuelCellInit
