cfdemSolverIBRO - Immersed boundary method (continuous focring approach)
solver for particulate flows. Does not provide the rigid body constrain
and provides approximate solutions for the faster simulations.
New immersed boundary solver based on the PIMPLE algorithm to handle
large Courant number flows. This solver is around 2 times faster than
the PISO algorithm solver.
Add switching term for particles crossing periodic boundaries.
Included the swicthing term in the velocity correction operation.
Considers rotation in CFD domain and does not consider rotation at
periodic boundaries.
Integrated the two-way coupling into cfdemSolverIB solver.
Changed the functionality of cfdemSovlerIBTorque for the bonded
multisphere solutions.
Added the relative velocity of spheres as a function in
cfdemCloudIBmodified to make it feasible for bonded multisphere clumps.
Inserted a per-molecule com based velocity calculation instead of using
individual particle velocities. Enables consideration of particle
rotation about molecule com.
Molecule data considered as per-atom properties. Consideration of
relative motion of atoms with respect to molecule centre of mass.
Rotation about the centre of mass.
Added the functionality to create and utilise fvOptions for the immersed
boundary solvers. This is useful for considering periodic channel flows
with meanVelocityForce momentumSource.
Corrected the torque calculation for the cfdemSolverIBTorque and
modified the ShirgaonkarIBTorque calculations.
Included fvOptions.H in the solvers for activation the usage of
fvOptions.
Now, environment variables are used, e.g. $CFDEM_VERSION. This closely
follows the set-up of OpenFOAM. Also, some settings were made similar
to OpenFOAM's setup.
Since OpenFOAM-3.0 it is the convention to put blockMeshDict into system
instead of constant/polyMesh
Having blockMeshDict in system is supported since OpenFOAM-2.3
The equation was probably taken from the paper of Kurose and Komori
1999, which does not repoduce the original formula given by Mei 1992
correctly (which itself is missing a left parenthesis).
The correct formula can be looked up for example in Mei and Klausner
1994 or Loth and Dorgan 2009
