Smoothed Particle Hydrodynamics provides a way to approximate field derivatives with a set of unstructured points. Due to its simplicity and ease of implementation, it has gained great traction for solving problems related to free-surface fluid flows. Unfortunately, due to several drawbacks of the conventional/traditional SPH formulations, it was never a massively popular choice for solving solid mechanics problems / non-newtonian fluid flow problems. To overcome the previous difficulties researchers have been facing when using SPH for such problems, I am developing new approaches based on total lagrangian SPH formulations and implicit time stepping schemes. These numerical methods can then be used as a framework simulate various additive-manufacturing situations, such as direct-ink-writing (DIW).
