Gazebo provides different world pose between two simulation instances

I am running Gazebo Simulation with applying constant force for 6 sec multiple times ( two different instances ). I found that, the robot poses are different in two instances. C:\fakepath\instant1_force.png C:\fakepath\instant2_force.png Here, force and simulation time is constant ( green color), while poses are different. Though, the difference looks very small, I want to ask, 1] Is Gazebo non-deterministic ? 2] Can we control this non-deterministic behavior ?

I found that, the robot poses are different in two instances. such that, x = 8.515776 in first instance and x = 8.514708 in second instance, and similar for y,z, roll, pitch and yaw.
