So I ran a simulation with a rocket and a motor and got a result. I then ran the simulation again, and the apogee altitude was a few meters different. I ran it again, and got another different but close apogee result.

Is there some sort of variability built into the simulation, or am I using it incorrectly?

I've not had that issue? Perhaps post up the .ork file so the folks can take a look at it.

Look at the simulation paramters by clicking [Edit Simulation]

Do you have turbulence and variable wind in your simulation? [I think the default is yes to both.]

There are non-zero values for average wind speed and std. deviation, so that must be it. Thanks.
