LATPRM, MINRAD

Parameter

Values

Description

MINRAD

Real > 0.0

Default = See Note 2

Depending on the LATPRM,CLEAN value, MINRAD is either used to set the Lower Bound of the Design Variables in the Lattice Sizing Optimization Phase, or the minimum radius value for Beam Cleaning.

If LATPRM,CLEAN,YES:

MINRAD controls the minimum radius of tapered beams during the beam cleaning procedure in the second optimization stage in lattice optimization.

Any Lattice beam element with radius lower than the specified MINRAD value will be cleaned/removed from the model. For example, if MINRAD=0.1, then any beam with radius lower than 0.1 is removed.

If LATPRM,CLEAN,NO:

MINRAD is used to set the value of the Lower Bound for Design Variables in the Lattice Sizing Optimization Phase.

Note:

1.	This parameter can possibly be set equal to the smallest dimension that a particular 3D Printing machine can generate.

2.	If MINRAD is specified in the input deck without any value, then the default value is set equal to . Where, UB is the upper bound of the design variables for Lattice Sizing Optimization phase.

3.	If R2LRATIO and MINRAD are both specified in the input deck, the max(R2LRATIO, MINRAD) value is used for beam cleaning. R2LRATIO does not affect the lower bound of the sizing design variables in the second phase.
