Use the Quality panel to check the quality of connectors and the realized
FE.
Location: Connectors module
The Quality panel is used to determine if the model contains duplicate connectors or if the
realized elements meet the quality requirements such as the length of 1D elements
and their perpendicularity to the shells they connect.
Connectors (Unrealized) Subpanel
Use the Connectors (Unrealized) subpanel to perform two different quality checks -
duplicate and adjacent connectors. Two or more connectors that are located within
the set tolerance and connect the same link entities (for example, Parts) are
considered duplicates. Two or more connectors that are located within the set
tolerance but connect different parts are considered adjacent.
Option
Action
connectors
Select the connectors for which you would like to check the
quality.
tolerance=
Specify the tolerance used to determine if connectors are
considered duplicate or adjacent.
preview duplicates
Find all the duplicate connectors in the entire model that
are within the tolerance of each other, highlight them in the
modeling window (display is enabled
if it was originally turned off), and place them in the input
collector (ready to delete one of each pair of
duplicates).
preview combine
Find all the adjacent connectors in the entire model that are
within the tolerance of each other, highlight them in the
modeling window (display is enabled
if it was originally turned off), and place them in the input
collector (ready to combine each set of adjacent connectors into
one).
remove duplicates
Find all the duplicate connectors in the selected connectors
and delete one of each pair of duplicates, thus eliminating any
duplicates in the model.
combine
Combine each set of identical/congruent connectors into one
connector that connects all the link entities.
Projection Check Subpanel
Use the Projection Check subpanel to locate connectors that are badly positioned, by
alerting you to welds whose length exceeds a tolerance that you specify. This check
works on realized as well as unrealized connectors. Figure 1. Correct Projection Length is the Distance Between n1 and n2
Option
Action
connectors
Select the connectors for which you would like to check the
projection length.
find too long/find too short/find too long or short
Select the type of error to check for.
find too long
Find welds that are longer than the projection
length.
find too short
Find welds that are shorter than the projection
length.
find too long or shor
Find welds that are longer and shorter than the
projection length.
length = /length = (T1+T2)/2
Define the projection length.
length =
Enter a specific "correct" length for connectors, so
that connectors deviating from it by more than the
tolerance will be located.
length = (T1+T2)/2
Use the average of the thicknesses of the parts
connected by the weld as the "correct" value:
(T1+T2)/2.
tolerance
Specify a tolerance to find the weld that deviate from the
projection length by more than this amount. The welds that
deviate by this amount or less will be ignored.
1D Elems Subpanel
Use the 1D Elems subpanel to check all of the 1D elements in the connector
realization for certain quality measures.
Option
Action
free 1Ds
Consider a 1D element free if one or more ends do not connect
to another element in the model.
Note: This check is valid only
for mesh dependent realization types.
length >
Fail 1D elements with a length greater than this
value.
angle >
Fail 1D elements that deviate from the shell element normal
by more than this value.
check
Perform all the selected checks and highlight the connectors
for which 1D realization elements failed at least one of the
selected quality checks.
save failed
Save the failed connectors (for which 1D realization elements
failed at least one of the selected quality checks) to a mark so
that you can retrieve them from other panels.
3D Elems Subpanel
Use the 3D Elems subpanel to check all of the 3D solid elements (hexa) in the
connector realization for certain quality measures.
Option
Action
length >
Fail hexa elements with a height greater than this
value.
jacobian <
Fail hexa elements for which jacobian is lower than this
value.
Jacobian is a measure of the deviation of an element
from an ideally shaped element. The Jacobian value ranges
from 0.0 to 1.0, where 1.0 represents a perfectly shaped
element. Jacobian value of 0.7 and above is generally
acceptable.
check
Perform all the selected checks and highlight the connectors
for which hexa realization elements failed at least one of the
selected quality checks.
save failed
Save the failed connectors (for which hexa realization
elements failed at least one of the selected quality checks) to
a mark so that you can retrieve them from other panels.
