This function is used to check
the interference state between parts. The elements with interference will be
displayed in grey. The control window of this function varies with the
different file types. If the d3plot file is opened, the control window
illustrated in Figure
5.15.1(a) appears. If the Nastran file is opened, the control
window illustrated in Figure
5.15.1(b) appears.

1.
BY PART GROUPS
If this option is toggled
on, the user needs to set the master part group and slave part group. This
function is used to check the interference between two part groups. There is no
checking of interference between parts within the part group. If this option is
not toggled on, the user may select any part. This function will only examine
the interference between any two parts.
2.
INITIAL INTERFERENCE
In some cases, the initial
model has interference in itself. The user may need to ignore or keep the
interference.
l KEEP
Filter the interference from
the initial model generated by the current step.
l REMOVE
Plot all the interferences
without filtering the initial model interference in the current step.
3.
CONTROL PARAMETER
l PENETRATION
This option is used to check
if there is penetration between elements of the parts.
l CONTACT
This option is used to check
if there is contact between elements of the parts.
l CONTACT GAP
This option is only used for
Contact interference. The value is the maximum allowable gap criterion to
distinguish the contact interference.
l TOLERANCE
This function is used to
control the calculation accuracy.
4.
PAUSE AFTER FAIL
Once this option
is selected, if there is interference in the animation state, the animation
will pause automatically after one cycle.
5.
IDENTIFY INTERFERENCE
This function is
used to identify the interfering element numbers and highlight them.
