What are some tips for improving accuracy in shallow water flow simulations?

[MartinV]

I'm trying to create a simulation of shallow water flow and I keep getting huge values of variables. Does anyone here have experience with this type of computer simulations?

What kind of stimulation?
What are you trying to find out?
what progam(s) are you using?

The problem with any surface simulation is modeling the interface. You have two different fluids doing their own thing.

what software or 3d engine would you do this in if you wanted to use c++?

I understand the challenges and complexities involved in creating simulations, especially for dynamic systems like shallow water flow. It is not uncommon to encounter large values of variables in simulations, and this can be due to a variety of reasons such as numerical instabilities, incorrect input parameters, or limitations of the simulation model itself.

I suggest carefully reviewing and validating your simulation inputs and parameters to ensure they are accurate and representative of the real-world scenario you are trying to simulate. It may also be helpful to consult with other experts in the field or seek guidance from published literature on similar simulations.

Additionally, consider using a more advanced and robust simulation model that can handle the complexities of shallow water flow, such as incorporating turbulence and sediment transport. This can provide more accurate and realistic results.

Overall, creating simulations is a challenging task and it often requires trial and error and continuous refinement to achieve accurate results. I encourage you to persist and seek help from experienced individuals in the field to improve your simulation.
