AMENV

AMENV, TGAS, HGAS
Specifies the build-environment thermal boundary conditions in an additive manufacturing analysis.

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

TGAS

Temperature of the gas in the build enclosure.

HGAS

Convection coefficient from the part to the enclosure gas.

Command Default

No convection is included.

Notes

If using the power-bed fusion process (AMTYPE,PBF), the convection is applied only to the top of a newly laid layer.

If using the directed-energy deposition process (AMTYPE,DED), the convection is applied to the top of a newly laid layer and to the sides of the part already built.

No convection boundary conditions are applied to the plate, although you can define them manually (SF and related commands).

This command is also valid in PREP7.
