* To-do list [#k43773e8]
- Must-do
-- normalize \phi_i by min{1, sum_i \phi_i}
-- MPI for larger scale simulation on cluster machine
-- AC shear flow with LE PBC
-- More inter-particle interactions such as DLVO and Morse potentials
-- Front-end-processor to create input.udf
- May-do
-- Fluctuating Hydrodynamics
-- MPI for larger scale simulation on cluster machine
-- Multiple particle size
-- Viscoelastic fluid
* Known bugs and limitations [#p38774d3]
- Abort when restart.udf is created (very rare). This may be a problem of libplatform.
