I use Rocksim for my rocket builds - much less experience with OR. However, a situation recently came up that requires me to identify potential OR model design "oversights" and I'd appreciate some clarification/ confirmation about what I think I'm seeing in this OR model. For various reasons I do not wish to post the ORK file so I'll try to be as clear as possible with my observations.
The majority of my concern is that I found what appear to be inconsistencies in the use of the OR component mass override.
- First issue: Some components have the Override Mass box checked but the Override CG box is not checked. Doing this in RockSim places the component CG at the extreme forward position of the component, which is not realistic. How does OR react under this condition?
- Second: Some components have the Override Mass box checked but there is a zero value entered for the mass. In this model the fins and the MMT
So the model has some component masses calculated (with the appropriate component CG, I assume), other components have mass overrides with zero mass values entered, and finally many of the components with overridden masses have no associated CG override values entered.
So which of these situations do the seasoned OR users say are problematic & why?
Thank you
