3D matrix defines thermal resistance values at multiple temperature
% and flowrate points. During the simulation, the actual value is picked 
% based on *FlwR* and *FlwT*. *FlwR* and *FlwT* specify coolant flowrate 
% and inlet temperature based on the values set.
% 
% *FlwR* — Value between 0 and 1, specified as a scalar. The *FlwR* input 
% value is used to dynamically choose the right value of the flow rate 
% during the simulations. The value of the *FlwR* input defines the actual 
% flow rate in the
