An error occurred while running the simulation and the simulation was terminated
Caused by:
The expression: (1/(9*10^(-6)+0.1*u(4)))*(u(2)*u(4)*u(3)*0.1+0.98*u(3)*cos(u(1)))
in 'HANANEE/Fcn2'
has a subscript that is out of range

I see that the Fcn block highlighted in yellow (giving the error message) is part of a closed-loop, where in order to get a result it needs to have all those input values, but some of those inputs depend on the output of the block. Try to run the model step by step via Debug mode.
Another point: The Fcn block is not longer recommended. See more about it here:
(Not recommended) Apply specified expression to input - Simulink - MathWorks Nordic
If possible try to use a MATLAB function block instead.
