The reason for going with 0.00

The reason for going with 0.0001 here was an attempt to make the division a little better numerically, as SMALL is 1e-15. The same term is multiplied in the laplacian equation later. I do not know if...

Good. Thanks for trying it out

Good. Thanks for trying it out. To get rid of the ugly entry, I believe you can give the term a name, which is then called in fvSchemes. In Ueqn.H for example, it is fvm::div(phia, Ua,...

Sorry, missed your message Alb

Sorry, missed your message Alberto. I believe that pEqn.H remains unchanged. The change in the code applies to the ppMagf-term, which is calculated in alphaEqn.H.

To expand the discussion. Although you could exclude the division of alpha in the ppMagf-calculation (for hard materials), the "bug", I believe, is in the laplacian-term. There ppMagf needs to be...

Sorry, but why is this term left out? According to the equations they should be there. With the proposed fix included I get expected results. Without it, physics are wrong and results suspicious. Try...

Description: The application

Description:
The application gives erroneous solution for the Ua-field when the particle-particle force is included (g0 > 0). If settling particles are simulated, the velocity of the particles does...
