I am working on simulating Selective Laser Melting (SLM) meltpool behavior in ANSYS Fluent(like the second meltpool picture of another paper), as depicted in the attached image. To create the geometry for this simulation, I have two options:
Option 1: Separate Rectangular Boxes Create a separate rectangular box for the baseplate. Create another box on top of the baseplate as the powder bed. Patch the baseplate and imported powder spheres as solid, and the rest as the air phase. Option 2: Single Domain Create a single domain encompassing both the baseplate and the powder bed. Define the particles and baseplate as solid and the surrounding area as the gas phase within Fluent. I am unsure which option to follow, especially considering that I need to apply a moving heat source to the powder particles. Additionally, I want to confirm whether my mesh is appropriate: I created a dense mesh in the powder bed zone and a coarser mesh in the baseplate zone. Could you provide guidance on which approach to take and whether my meshing strategy is suitable?Geometry Mesh.jpg Meltpool.jpg |
