How can I get the instantaneous step size value in variable step solver at a simulink model?

This is an urgent stuation. I got a proble to get the value of instantaneous step size value in variable step solver. In my simscape model there is also a runge kutta solver function that I wrote and I need a h value which is a h=step_value/10. I dont want to use fixed step solver. That is why I need to know step value for each time step. I would be appreciated if you help me.

Hi, you can use the "Clock" block in Simulink to get the current simulation time and the "memory" block to store this value for each step. In each step, subtract the output of "Memory" block (i.e. previous time step) from the current output of "Clock" to get the current step size. Here is a sketch of the workflow:
I hope this helps!
