3.1. Introduction This lab focuses on running a simulation and viewing the results in the DEFORM™-3D Post- rocessor!
3.. O!"nin# $ Pr"%iou'( S$%"d Pro)'"* "f DEFORM is not alread# oen$ oen it as #ou did in the revious lab! %hen the M&"' window oens$ clic( on the )*O+, folder in the Director# list and then highlight the )*O+,!D) file in the file list!
3.3. St$rtin# t+" Si*u'$tion ou are now read# to start the simulation b# clic(ing list!
The
rogress
of
the
simulation
can
be
monitored as it is running b# loo(ing at the Message file! +lic( the Message tab to view the Message file! &s long as the otion is chec(ed$ which is the default setting$ the Message file will refresh ever# coule of seconds! The Message file rovides information about which
simulation
ste
the
simulation
is
currentl# on and also gives information dealing with how well the simulation is running!
in the
DEFORM™-3D *abs
%hen the simulation has finished$ the following message will be added to the end of the Message file/
3.,. Pot-Proc"in# t+" R"u't &fter the simulation has comleted$ clic( on
under
! The DEFORM-3D Post-rocessor will aear!
3.4.1. Step Selection To select the ste to be viewed$ there is a ste list ull-down menu at the to of the window! 0se the ull-down list to select a ste!
3-.
The
icon can be used to bring u the 1TEP *"1T window$ which allows the user to
define more detailed ste settings! The following buttons are also available for selecting a simulation ste/ First 1te One 1te )ac( Pla# )ac(ward 1to Pla#ing Pla# Forward One 1te Forward *ast 1te Pla# through the stes to loo( at the deformation of the wor(iece!
3.4.2. State Variables 1ome of the most commonl# used state variables can be viewed using the 1tate 2ariable ulldown menu at the to of the window!
1elect Strain--Effective from the list to loo( at the amount of deformation the wor(iece has undergone! +lic( the
icon to bring u the 1T&TE 2&R"&)*E window$ and select
as the Scaling otion! This otion will use the global Min and Ma effective strain as the etremes on the color bar! Pla# through the stes of the simulation to observe the accumulation of strain! The 1tate 2ariable ull-down list onl# shows a coule of the variables that can be lotted! The
icon can be used to access all of the state variable otions!
3.4.3. Point Tracking "n DEFORM it is ossible to trac( oints in an ob4ect through the simulation! 'ot onl# can the osition of the oints be trac(ed but also the state variables at those locations! To oen the PO"'T TR&+,"'5 window$ clic( the
icon!
%e want to define several oints on the undeformed geometr# and see where the# go as the art deforms! To view the undeformed geometr#$ clic( the
button to view the first ste of the
simulation! 'ow clic( three locations on the wor(iece 6close to those shown below7 and clic( the
button!
&ccet the default Tracking Option and clic(
!
"f Effective 1train was still being lotted in the D"1P*& window$ then a Point Trac(ing lot will aear showing Effective 1train vs! Time for the three oints that were selected$ and the following will get added to the Ob4ect Tree/
"f no state variable was being lotted when the oints were trac(ed$ then the following will be shown in the Ob4ect Tree/
%hen a state variable is selected from the 1tate 2ariable ull-down menu$ the oint trac(ing grah for the three oints will aear in the D"1 P*& window! +lic( the
icon to la# the through the stes! ou will notice that the corresonding ste on
the Point Trac(ing lot also gets highlighted as the stes change! +lic( the
icon to sto the
ste la#bac(! 'ow clic( an#where on the Point Trac(ing grah - the selected ste shown in the D"1P*& window should change to match the location selected in the grah!
3.4.4. Slicing Objects "n DEFORM-3D it is ossible to slice an ob4ect and then view different state var iables within the ob4ect! *et8s first hide the Point Trac(ing grah b# right-clic(ing the Point Trac(ing in the Ob4ect Tree and selecting the Hie PointTracking otion!
+lic( the
icon to oen the 1*"+"'5 window! The ob4ects can be sliced in several different
wa#s! The ob4ects in the D"1P*& window have a #ellow rectangular bo surrounding them! )# clic(ing on a vertical edge of the bo$ a hori9ontal slicing lane will be created! )# clic(ing on a hori9ontal edge of the bo$ a vertical slicing lane will be created! +lic( the #ellow bo in several locations to eeriment with this slicing otion!
The slicing lanes are defined b# a oint on a lane and a normal direction to that lane! These are designated in the 1*"+"'5 window b# P 6Point7 and ' 6'ormal7! The ob4ects can also be sliced b# selecting the :$ $ or ; coordinate of the Point and then using the slider bar to drag that coordinate u or down! &s the slider moves$ the ob4ects will be d#namicall# sliced! +lic( the : coordinate of the Point$ as circled below$ and then drag the slider bac( and forth to slice the ob4ects!
1everal otions are available for determining how the sliced surfaces are disla#ed!
