Detailed Description

This example is derived from

Meier et al. 2020 "A novel smoothed particle hydrodynamics formulation for thermo-capillary phase change problems with focus on metal additive manufacturing melt pool modeling"

and

C. Ma, D. Bothe 2011, "Direct numerical simulation of thermocapillary flow based on the Volume of Fluid method"
