Non real time simulation

I am looking to use unreal engine’s powerful capabilities to vizualize a robot simulation in a 3d scene with a 3rd party program (math package). I want the ability to perform non-real time simulation. Basically I want my other program using the math-package which has its own notion of clock-time to define robot physics, joint movement and control while using UE to vizualize the robot as a Pawn. The question I have is - is it possible to control how the UE4 game Ticks such that I can keep the clock in the 2 programs in sync with each other? Currently I don’t see options to control the game’s clock tick events or ensure that they have predictable periodic increments or make the game run in non real-time mode.

Solved - I can use -benchmark -fps 30 to run the game non-wall-clock time and render every single frame.
