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.
