[EDEM] Dose EDEM Support running more than one API ContactModel at once?

KJHSNU

Hello,

I am currently developing and using an EDEM API-based contact model. Recently, I created two custom contact models using the API. Each model works correctly when tested individually; however, I found that when both are applied simultaneously, neither of them is activated.

At first, I considered that this might be due to the order of models in the Creator – Physics panel. However, if that were the cause, at least one of the models should still have been applied, so I believe this is not the underlying reason.

Therefore, my question is: is it fundamentally impossible to use two API plugin contact models at the same time? In other words, does EDEM not support running more than one plugin API contact model concurrently?

Thanks in advance!

Hi,

You can run multiple contact models at the same time. The models chain the forces and values. So whatever force is calculated in the first model in the chain, this is passed down as an input to the second model and so on.

It's worth noting that if the first model calculates a force, passes this down the chain to the second model, and the second model uses results.force = value rather than results.force += value then the "=value" will overwrite the previously calculated force. "+=" will add to it.
