Query: A Consistent Parallel Isotropic Unstructured Mesh Generation Method
  based on Multi-phase SPH   In this paper, we propose a consistent parallel unstructured mesh generator
based on a multi-phase SPH method. A set of physics-motivated modeling
equations are developed to achieve the targets of domain decomposition,
communication volume optimization and high-quality unstructured mesh generation
simultaneously. A unified density field is defined as the target function for
both partitioning the geometry and distributing the mesh-vertexes. A
multi-phase Smoothing Particle Hydrodynamics (SPH) method is employed to solve
the governing equations. All the optimization targets are achieved implicitly
and consistently by the particle relaxation procedure without constructing
triangulation/tetrahedralization explicitly. The target of communication
reduction is achieved by introducing a surface tension model between distinct
partitioning sub-domains, which are characterized by colored SPH particles. The
resulting partitioning diagram features physically localized sub-domains and
optimized interface communication. The target of optimizing the mesh quality is
achieved by introducing a tailored equation-of-state (EOS) and a smooth
isotropic kernel function. The mesh quality near the interface of neighboring
sub-domains is improved by gradually removing the surface-tension force once a
steady state is achieved. The proposed method is developed basing on a new
parallel environment for multi-resolution SPH to exploit both coarse- and
fine-grained parallelism. A set of benchmarks are conducted to verify that all
the optimization targets are achieved consistently within the current
framework.
