Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality and create, edit, and apply
shapes for subsequent design optimization studies.
Create weld points at a predefined pitch distance so that the model build process can continue without the need to
wait for the published weld data from CAD. Autopitch is useful when working with elements, not geometry.
The Design Space environment is dedicated to topology optimization model build and setup. It facilitates rapid model creation by generating
the voxel design space for a number of different use cases.
Many essential utility tools using HyperWorks-Tcl have been developed over the years to support Aerospace customers. A few tools have been collected and upgraded to
be compatible with this release.
Restriction: Available in Abaqus, LS-DYNA, Nastran, OptiStruct, and Radioss.
Creates one hexa cluster per connector and realizes a node to node connection to the
linked shell meshes by adjusting it (shell coating). Different patterns are available.
This is driven by the number of hexas. The appearance can be influenced via the diameter
and the washer layer activation.
For LS-DYNA, the property script
prop_acm_coating.tcl is used.
ACM Realization Options
Option
Action
thickness
Select a thickness
option used for dimensioning and positioning hexas.
shell gap
Project the hexa spot to touch the shell
elements.
The position is independent from any thickness.
equival. (T1+T2)/2
Create hexa elements with RBE3 elements projecting
and connecting to the surrounding shell
elements.
This realization uses the shell thickness to
calculate the hexa offset from the shell elements.
In the case where the model is a 3T connection, the
acm (equivalenced-(T1+T2)/2) realization will join
the hexa elements.
detached (T1+T2)/2
Create hexa elements with RBE3 elements projecting
and connecting to the surrounding shellstr
elements.
This realization uses the shell thickness to
calculate the hexa offset from the shell elements.
In the case where the model is a 3T connection, the
acm (detached-(T1+T2)/2) realization will not join
the hexa elements.
mid thickness
Calculate the hexa spot size (thickness) as the air
gap between the two connected parts. If there is no
gap, or even a penetration, the hexa spot size will
always be modeled with 1.0.
const thickness
Specify the hexa spot size (thickness).
maintain gaps
Calculate the hexa spot size (thickness) as the gap
distance reduced by two times the specified value
for maintain gaps.
The position is independent from any thickness.
num hexas
Create a hexa cluster
with 1, 4, 8, 12, 16 or 32 hexas, which are arranged in a
predefined pattern.
Note: Available for all ACM realization
types.
coats
Define the number of
hexa elements required along the thickness. Multiple solid coats
are supported.
orthogonal
faces
Force the creation of
perfectly orthogonally-shaped hexas.
Note: Available for any kind of ACM weld, if num hexas is
set to 1.
