Dear All,

I want to simulate cyclone separators by MPPICFoam. For that, I draw a cyclone configuration in Catia and then by applying snappyHexMesh, the grids(meshes) were produced. When I used transformPoints to change the dimension of this configuration into millimetre and then applying MPPICFoam. But after some seconds I have this message:

....

To remove this error, I checked all files to be sure about accuracy of them. Moreover, I tried to simulate that problem without any turbulence and again I faced by that message. Then, I considered that problem without any particles and found that the problem solution is working but as soon as particles are considered, the simulation is not working and I have above message. Till now, I could not find what the problem is and what I should do to remove this problem and run my simulation.

Could you please guide me?!!!

Dear Dosin,

I work for CONSELF - https://CONSELF.com. the good news for you is that in march we are going to release a new version of our web application which contains the feature you have asked. Just to show you the cyclotron executed by us: https://youtu.be/ntnWJC93voQ
