1 way coupling: CGNS

Kiran Purushothama Keshavan

Hi,

I'm using the one way coupling using the API. I'm trying to simulate the fluid particle interaction for low density particles falling from a height (Fluid media is air), the problem here is the force field generated does not account for enough forces on particles at even high velocities (80m/s), is there an alyternate method/ formulation for Ftotal that I can use in the API for low density particles?

Thanks,
Kiran

Hi Kiran

If you are using the API, you have the flexibility to change the code according to your requirements. Please take a look at the .cpp file, and then you can modify the equations according to any reference that you'd like.

Hope this helps.

Hello,

Thanks for your reply, do I have to recompile the dll each time I use a different fields.cgns file?

Hi Kiran

You have to recompile the .dll each time you make a change in the .cpp file, but you do not have to recompile each time you update the CGNS field. Depending on where in the code the field is read, you may have to reload the plugin model after changing the CGNS file, but you do not have to recompile it.

Hope this helps.

Hi Kiran,

As long as your mathematical functions/Physics are the same no need to update dll but whenever you try to re-run the EDEM simulation you try to click on the refresh button next to the dll option.
