Rework existing flow simulation or supply own version

I wish to have a simulator which shows the effect of small particles in a flow of water and their interaction with obstacles due to gravity and flow dynamics. There is an open source flow simulator written in Java and which combined with code from other sims on the same website should make most of what I want to achieve. The flow simulator and other sims can be found and tried at ( [url removed, login to view] )

You should be able to navigate to the questions area and there is the link for the source code for all the sims. Some are HTML5.

If someone has another way to do this such as using Discrete Element Method (DEM) or whatever, that's fine, but this project is not intended to be some professional simulator, it is only for my own study of sand-like sized particles flowing over various terrain/obstacles.

The main points that I can think in relation to modifying the simulator I posted the link for above are...

-The particles in the water have a slider or other user input to adjust density and therefore react to gravity accordingly. There are gravity sims on that site which the code can be taken from. It would be nice to have three or so different particles of differing densities at the same time.

- There is a way to add obstacle/terrain shapes along the path of the flow.

- There is a slider to adjust the size of the particles for each density.

I have attached a jpg drawing which shows an alternative version where I can draw the bottom terrain of the container along a finite length. The particles would then flow along that surface. This would be the ideal way to do what I want to achieve, but if that is not possible then the modified sim mentioned above with movable obstacle shapes will have do.

Programs are available that can do this, like solidworks flow and commercial DEM software, but this project is very specific and I only want to do this one thing so no use paying for an expensive program. If anyone wishes to use some open source DEM software to make this work fine, but please remember this is a small budget project for my own study and must be priced accordingly. I think it will be easier if someone already has some experience in this field.

Thank you for reading this and I look forward to any replies.

As I have had one bid where it is obvious the bidder can't read English and just put a spam bid, please don't bid unless you can do this within budget.

I can work on your project. However, it is much bigger and time consuming than you realize. Most likely, it would take about two months to finish it, and obviously cannot be done for the amount you are suggesting. That More
