simulation

Alright, If any of you have followed or seen GPS Drift, an excel spreadsheet that helps you predict the landing location of your model and high power rockets. I wrote it back in 2021. @MarsLander recently reached out about a weathercock addition to the sheet. This was added and released -...

I am currently in the process of making a 2 stage rocket, and simulations are very important for such a project so I wanted to try Rocketpy. The only problem is that I couldn't find anywhere how to make a 2 stage rocket inside of rocketpy. I searched everywhere, I couldn't find any resources...

We are excited to announce the arrival of RocketPy v1.0.0a1, the alpha version of our v1.0.0 which is coming soon! RocketPy has been soaring high, and this release marks a major milestone in its development. We have listened to your feedback and worked tirelessly to bring you an exhilarating...

Calling out all Rocketeers and Developers!! We are excited to announce the first open RocketPy Hackathon! Don't miss the opportunity to participate! Develop your teamwork skills and learn more from our open-source library. You can show your interest and pre-register by filling out the form...

I wanted to verify our apogee (and the rest of the flight) predictions between OpenRocket and RaeAseo II. After importing the rocket into RasAero II and making sure that everything matched the OpenRocket, I ran the simulation and found that the apogee varied between OpenRocket and RasAero II by...

Out of a desire to understand a little more where my rockets could potentially land leading up to the launch, and the morning of launch. As well as predicting where anomalous flights may go(main at apogee failures anyone?) Especially after having treed a couple rockets in my close flying circle...

When using the engines given by our rocket open rocket, there is no problem in the parachute system. Since we are given a different engine in the competition we will enter, we upload its file. When we simulate it acts like a parachute is not added. What do we have to do? Please help me.

Hi all, I just got Open Rocket to simulate an F powered rocket that I'm building, and for some reason, I can't get the stability number past 0.6! I've tried everything. Any ideas on what to fix?

Hi everyone. I build a rocket in Open Rocket. I have a problem when run simulation. I uptaded .org file and a picture that shown error message. What is the solution of the error? Thanks

Simulating my first large rocket on RasAeroII and am really paying attention to the details. After reading the whole manual, I know to enter takeoff weight, and CG under Flight Performance, double tapping the loaded sustainer motor (single stage). In order to get an accurate sim, I am assuming...

Silly thought, but one I had in the shower earlier today. Is there any way to simulate parallel staging in a cluster? Specifically, I'm thinking of a situation where you'd have several very large motors strapped together in a cluster, and then only certain sets (in symmetrical pairs) would be...

In the view of the advantages of working with lines of code in an batch way (scripted in Java), I would like to know if there has been anybody able to run any kind of simulations of Open Rocket from a Java code, even of a simple rocket. Is there an standard example of code somewhere, used to...

I am relatively new to the rocket simulation world and I am looking to leverage the knowledge and experience of those that may be further down the road. I'm currently using RockSim as I've been simulating various part and engine configurations for a 1.68x Orbital Transport booster / glider...

Hi there, I wonder if it is possible to run a simulation in OpenRocket without the need of the GUI or the need of interact with the GUI. I am aware of simulation listeners, but these require some interaction with user interface. In brief, I want to run a simulation and get its results without...

Hi all, I'm working up for my L3, which is going to be a fiberglass Madcow DX3 XL (black Friday special), with (tentatively) an M1350 motor. Going with the KISS principle, I'm planning to do it "stock" with the addition of a thrust plate. My problem is keeping the thing within our altitude...

Hi, Everyone what's up! :D Puns intended...lol....I'm new to the forum. Where can I find OpenRocket Sims for an Estes Goblin? Thx
