how to solve the integer multiple of fixed-step size

when play the drive train

Invalid setting for fixed-step size (10000000.0) in model 'Drivetrain'. All sample times in your model must be an integer multiple of the fixed-step size.

Component:Simulink | Category:Model error

The sample time period (5.0E-5) of 'Drivetrain/Drivetrain/Discrete-Time Integrator ' is not an integer multiple of the fixed step size (10000000.0) specified for model.

Component:Simulink | Category:Model error

The sample time period (5.0E-5) of 'Drivetrain/Drivetrain/Discrete-Time Integrator1' is not an integer multiple of the fixed step size (10000000.0) specified for model.

Hi,

The Fixed-step size is the time interval after which the solver solves a Simulink model. Hence, all the sample times in a Simulink model must be an integer multiple of the fixed-step size. In your example, the fixed-step size is 10000000(e7). And the sample time for the block 'Drivetrain/Drivetrain/Discrete-Time Integrator' is '5e-5', which is not an integer multiple of e7.

To solve this issue, you can set the fixed-step size of the model to be 'auto'. You can find this settings in the Solver > Solver Details > Fixed-Step Size in the Model settings.

Hope this helps

Hi, I have the same problem and i tried this method but it didn't work

Error:The sample time period (0.00034722222222222224) of 'simulation/PMU (PLL-Based, Positive-Sequence)/PLL (3ph)/Model/Automatic Gain Control/Positive-Sequence (PLL-Driven)/Mean (Variable Frequency)2/Model/Digital Clock' is not an integer multiple of the fixed step size (5.0E-5) specified for model.
