alternative method for ggi
 
Dear Foamers

I'd like to simulate a dense suspension in a axisymmetric geometry with rotor and stator. My problem is that in OF16-ext it exists the ggi for dynamic mesh but no particle solver with particle-particle-interaction. And in OF201 there exists a particle solver with pp-interaction but ggi does not exist. I'm not experienced enough to program my own solver in OF16-ext.

Can anybody tell me what the alternative method for ggi is in OF201?

MRF does not work because the simulation should be transient. Are there some other alternatives?

Thanks for your help.

Have a look at

To be specific at:

(there are some examples with GGI)
