AMBEAM
AMBEAM, NUMBEAMS
,
POWER
, ABSORPTIVITY
Specifies energy source parameters in an additive manufacturing analysis.
NUMBEAMS
Number of beams used in the build process. Default = 1.
POWER
(Optional) Beam power for the build process.
ABSORPTIVITY
(Optional) Beam absorptivity value. Must be between 0 and 1. Default = 1.
Command Default
One beam is used in the build process.
If POWER
is not specified, the melting
temperature will be used for heating steps.
ABSORPTIVITY
is only used if
POWER
is also specified.
Notes
This command is also valid in PREP7.
For the POWER
option, if a value is
specified, then POWER
* ABSORPTIVITY
will
be used with other process and geometric parameters (scan speed, hatch spacing, deposition
thickness, heating time, superlayer volume) to define the heat generation to heat new element
layers. The heating time for this option is specified with the AMBUILD,TIME
command. If a POWER
is not specified, new layers will be set to the
melting temperature (AMMAT).
