Realistic Flight Model X-Plane uses blade-element theory to calculate the physics of flight, providing a very realistic flight model compared to other simulators.
Extensibility X-Plane supports a wide range of add-ons and plugins, including custom aircraft, scenery, and tools, making it highly extensible.
Cross-Platform X-Plane is available on multiple platforms including Windows, macOS, and Linux, allowing a diverse user base to access the simulator.
Regular Updates The developers of X-Plane consistently release updates that include new features, bug fixes, and improved performance.
VR Support X-Plane offers robust support for Virtual Reality (VR), providing an immersive flying experience.
Possible disadvantages
High System Requirements X-Plane requires substantial computing resources, particularly if you're running it with high graphics settings and multiple add-ons.
Steep Learning Curve Due to its realistic approach, beginners may find X-Plane challenging to learn without prior knowledge of flight dynamics and aviation.
Price X-Plane can be expensive, especially when considering the cost of additional plugins, high-quality third-party aircraft, and scenery packages.
Less Focus on Scenery Compared to some other flight simulators, X-Plane's default global scenery is not as detailed, which may detract from the visual experience for some users.
Occasional Bugs Despite regular updates, occasional bugs and performance issues can affect the user experience.
Open Source OpenSPH is open source, allowing users to access, modify, and contribute to its development, fostering a collaborative environment.
Scientific Computing It is designed for scientific computing, providing tools that are specifically tailored for simulations in astrophysics and fluid dynamics.
Customizability The software allows for significant customization and flexibility, helpful for researchers with specific requirements for their simulations.
Community Support Being open source, it benefits from community support, including forums and potential peer collaboration.
Possible disadvantages
Complexity The software can be complex to use, especially for individuals who are not familiar with scientific computing or fluid dynamics.
Documentation Sometimes open source projects may have sparse documentation, which can make it difficult for new users to learn and troubleshoot.
Limited Audience Its specialized nature means it is primarily useful to a niche audience, such as researchers and scientists, rather than general users.
Resource Intensive Running large simulations can be resource-intensive, requiring powerful hardware to perform efficiently.

Overall verdict
OpenSPH is a solid, specialized open-source tool for smoothed particle hydrodynamics simulations, particularly well-suited for astrophysical applications like asteroid collisions and planetary impacts. It's free, actively developed by an academic researcher, and produces high-quality scientific visualizations.
Why this product is good
Free and open-source, making it accessible for researchers, students, and hobbyists without licensing costs
Specialized for astrophysical SPH simulations such as asteroid collisions, fragmentation, and gravitational reaccumulation
Includes both a computational core and a GUI for visualization and analysis of simulation results
Developed and maintained by an active researcher (Pavel Ševeček), grounded in peer-reviewed scientific methods
Supports N-body gravity and material strength models relevant to planetary science
Well-documented with examples suited to academic and scientific use
Recommended for
Astrophysics and planetary science researchers studying asteroid and planetary collisions
Graduate students and academics needing an SPH simulation framework
Scientists requiring simulations of fragmentation and gravitational reaccumulation
Developers and hobbyists interested in open-source physics simulation code
Educational settings teaching computational physics and hydrodynamics
X-Plane and FlightGear are easily the most realistic but also the most complex. X-Plane costs $59.99 whereas FlightGear is free but X-Plane is more polished and easier to get going with than FlightGear.

Where could I find X-Plane 7?
Oh, Thanks !
I wasn't expecting to be able to download on the WayBackMachine
I tried on the old x-plane.com website with no success but it worked on boostair.com !

Error 47?
Has anybody gotten the "transaction failed (error 47)" message when trying to check out on x-plane.com? I've been trying to buy XP12 and I repeatedly get hit with this message :(.
