LIQUID
Implicit solver for incompressible and weakly compressible flow phenomena
The most advanced solver in the complete MESHFREE framework. It can handle incompressible or weakly compressible flow phenomena, i.e. the
solver accepts density formulations that might depend on time, pressure, and all other parameters needed.
