Non-uniform particle density
It seems in the GenCase, only uniform particle density can be used. Will the solver accept non-uniform particle densities?
If the solver accept, i think maybe i could manually generate the floating object (import complicate geometries from STL) using higher particle density while the fluid can use smaller density. This may be helpful in providing more accurate results while saving calculating efforts i hope.

See attached the _def.xml file for reference.
With the current online version we can only create particles with fixed dp for fluid, bound and floating, sorry!

When you use different "dp", then we will have different "h", so that different cell sizes for the neighbour list....... In addition the governing equations... when computing interaction between two particles of different "h" need to use kernel functions defined for different "h" lengths.....

@Alex Can you suggest how to simulate or modify the source code, if it was another non-uniform property of the floating body such as thermal conductivity, that doesn't affect the particle spacing?
