AMMeltpoolThermoFluidics is a C++ code developed to model heat conduction and fluid flow in a complex laser powder bed fusion process in Additive Manufacturing. The NonDimThermFluid has a finite-element code that models the relevant physics of the metlpool and has input parameters in terms of dimensionless numbers. The other branches have code suitable for different simplified problems which were used in the development of the model. The salient features of the computational implementation are: high-fidelity MPI-based parallel implementation, support for iterative solvers with preconditioning, and fully implicit time-stepping schemes.
AMMeltpoolThermoFluidics code builds on top of the deal.II library.
