error after 24 seconds in model

component divide

% PS Divide :0.75

% This block divides the first input signal by the second one:

% y = u_1 ./ u_2

%

% All connections are physical signal ports.

inputs

I1; % Left input signal (numerator)

I2; % Right input signal (denominator)

end

outputs

O; % Output signal (result of division)

end

equations

epsilon = 1e-1; % Small value to prevent division by zero

O = I1 ./ max(I2, epsilon); % Apply regularization to denominator

end

end

Hi @harsh,

The error that you are encountering during simulation of the model can be eliminated by using the following steps.

You can select 'Use local solver' in the ‘SolverConfiguration’ block if it is present in the model.

This allows Simscape and physical network components to utilize a specialized local discrete solver. The local solver treats the physical network as a stiff system, using an implicit solver to iteratively find the solution for the next time step with an algebraic solver.

To learn more about making optimal solver choices for physical simulation, you can refer to the following documentation:

Hope it helps!
