For exemple, when V<0.1 appear in Matlab window: "Voltage error!"

Hi,
it exists a block called MATLAB Function. Simply take this block and take the voltage as input signal. In this Block you can use normal MATLAB syntax and you could write
%warning is displayed
warning('warn text')
%or error is displayed
error('error text')

You could also use the the blocks in the Model Verification library, such as Check Static Lower Bound. Set the lower bound to 0.1 and set the callback to something like:
disp('Voltage error!')
You can uncheck the Stop simulation option if you want the simulation to continue even after this condition has been detected.

I don't know Simulink, but I think it can run MATLAB commands such as
uiwait(warndlg('Voltage Error: Voltage < 0.1!'));
