Sample files for use with the examples are available from the Downloads page.
Expand the downloaded ZIP archive into a convenient directory from which to run Local Simulation inside the numbered directories.
For this example, you will run commands inside directory 13.
This example utilizes multi-layer moving adaptivity to investigate peak temperatures during Laser Powder Bed Fusion processing. There are two simulations in this example: one that shows peak temperatures only after the final layer, and another that shows how peak temperatures develop over the deposition process. Both simulations use a 150-W source moving at 600 mm/s to simulate the melting of two layers of Inconel 718 powder, on a sample 0.5 mm × 0.5 mm square with 12.5-mm substrate. A surface convection of 10.d-6 W/((mm2)°C) is applied on the top surface and all other faces are insulated. The *ADPM card is used to control the acceptable temperature gradients across an element for coarsening, using the default settings. For both simulations the *LFUS card is used with a value of 1200° C, to investigate lack of fusion. The mesh and laser path are automatically generated using Local Simulation.
