multiscale simulation additive manufacturing openvdb AMR

Multiscale Model

Melt pool is fitted by a fine mesh. Fluid dynamics is simulated in a small region around the melt pool (~ 1 mm). Heat transfer is simulated in a large domain (~ 1 cm) with adaptive mesh step. Geometry of the powder and melted metal is stored as fine sparse volumetric data in the whole region (~ 1 cm).

Pores formation

High performance enables high mesh resolution. Small pores (~3 mkm) are resolved in geometry. Gas pressure in pores is reproduced.

Laser or Electron Beam source

Multiple reflections ray tracing for laser sources. Monte-carlo scattering for electrons in the volume.

Universal Input and Output formats

Universal input (JSON, stl, vdb) and output (vdb, vtk, data and image files) data formats. Output of both raw data (temperature, velocity, geometry) and post-processed data (meltpool size, total absorbed energy, etc.) is possible.
