In summary, the conversation discusses the topic of missing matter and the use of simulations to study it. The individuals are seeking advice on which programming language to use for their project and are recommended to look into N-body simulations such as NEMO or GADGET. The use of finite element analysis is also mentioned as a potential approach.

"Missing Matter"

Heyy Dear friends,
I and two of my friends 'll start to make a new project based on "dark matter problem".We are trying to make a simulation on galaxies which have diffrent surface density that is one of the parameters we have to determine. There are also other parameters.
However, we don't know exactly which program language should be chosen? If there anybody knows the suitable program name for simulations, i want to help from him.
Thanks

Hi physicsatiztech, welcome to PF! Missing matter problems abound in cosmology. Not just rotation curves in galaxies, but in clusters, super clusters and the universe at large. Numerical simulations are normally applied to such problems. The computational power required is enormous - even by todays standards. Finite element analysis [an engineering thing] would, IMO, be a great approach, but would require a very bulky computer [unless you broadly categorize the variables]. It is a hairy problem - even without invoking black holes.

Yepp, if you want to do it in any detail you'll need a super-cpu.

The standard numerical approach to this is to use what are called N-body simulations. Rather than re-inventing the wheel I would looking at some of the exisiting N-body programs. Try Googling 'NEMO' (with N-body, or you'll just get fish!) or GADGET (also with N-body or you'll just get cartoons!). These are both standard N-body packages. You'll need a C compiler, preferably on UNIX or LINUX to run GADGET. I'm not sure about NEMO but it's almost certainly written in C or FORTRAN.
 

FAQ: Dark Matter Simulation: Help Choose a Program Language

What is dark matter and why is it important to simulate?

Dark matter is a hypothetical type of matter that is believed to make up approximately 85% of the total matter in the universe. It does not interact with light and therefore cannot be detected using traditional methods. Simulating dark matter allows scientists to better understand its role in the formation and evolution of the universe.

What factors should be considered when choosing a programming language for dark matter simulation?

The programming language chosen for dark matter simulation should have strong numerical and computational capabilities, as well as the ability to handle large datasets. It should also have a well-developed library of scientific and mathematical functions, and be optimized for parallel computing.

What are some commonly used programming languages for dark matter simulation?

Some commonly used languages for dark matter simulation include C/C++, Fortran, and Python. These languages have been used extensively in various scientific fields and have libraries and frameworks specifically designed for scientific computing.

Are there any advantages to using a specific programming language for dark matter simulation?

The choice of programming language can greatly impact the efficiency and speed of the simulation. For example, C/C++ and Fortran are known for their speed and low-level control, while Python is more user-friendly and has a larger community for support.

Are there any challenges associated with simulating dark matter?

One of the major challenges of simulating dark matter is the lack of understanding of its properties and interactions. This makes it difficult to accurately model and simulate its behavior. Additionally, the immense computational power and resources required for simulating large datasets can be a limiting factor.
