There are at least 3. I like all of these. They all have their advantages & disadvantages.
RASAero II: https://www.rasaero.com/
OpenRocket: https://openrocket.info/
Thrustcurve: https://www.thrustcurve.org/

Open Rocket is going to be most intuitive. Measure the dimensions of rocket parts and weigh them as building. RAS is good when you want to go really really fast.
