DM.check-c / check13

"Swiss Army knife" for all kind of contact warnings.

The tool helps to analyze initial penetrations of the different contact definitions. It also helps to visualize the nodes moved during initialization by LS-DYNA due to detected initial penetrations.

usage:

check13 [options] message-file[s]

check-c [options] message-file[s]

options:

-list	list all warned penetrating nodes
-top ##	list and output top ## values (default: ##=5)
-ptol ##	list and output only penetrations > ##
-sid #,#,…	check only SIDs #,#,…
-bucket	show penetration buckets for each interface
-pid	print property for penetrating node
-psum	print property penetration summary
-rsort	sort for remaining distance default: sort for penetrating distance
-rtol ##	list and output only penetrations that have a remaining distance < ##
-title	print contact titles if available (read d3hsp-file)
-hsp	d3hsp filename if other than "d3hsp" (needed for -title)
-typ	print contact type (eg: a3, 13, a13)
-typ -typ	print contact type in keyword (eg: SINGLE_SURFACE)
-timestep	print contact timestep if available
-all	list all contacts (even without any warnings) (usefull with -timestep and -typ)
-g	optional d3plot-file (needed for property info) default: d3plot
-sel	selected warning type (default=all) values for in tied contacts: tied - all warnings for tied contacts sep - nodes with separation that are moved offset - nodes with separation that are not moved for any reason far - nodes with separation that are too FAR away (node is untied) short - nodes with separation that would shorten connected beams (node is untied) notfound- nodes that are not found to lie on any master segment (node is untied) rigslav - nodes that are rigid slave nodes (node is untied) rigmast - nodes that are found on master segment with any rigid node (node is untied) conflict - nodes that conflict with other tied contact definition (node is untied) untied - all above warnings with untied nodes (untied nodes of spotwelds should be corrected) values for in standard contacts (eg typ13): typ13 - all warnings for standard contacts that follow below pen - nodes penetrating segment mid - nodes close to shell midplane del - nodes deleted from contact after initialisation below - nodes too far below surface soft2 - element-element contact warnings in soft2 contact inter - element-element intersection warnings in soft2 contact (first state) last - element-element intersection warnings in soft2 contact (last state) curve - element-element intersection warnings in soft2 contact - LSPP XYcurve output and create LSPP XY plotfile "soft2_xy.crv" mortar - element-element penetration warnings in mortar contact types
-tlast ##	upper time limit for checking of "-sel last"
-key	create LS-DYNA keyword file "check13.key" with beams of length of the penetrations - can be loaded into LS-Post or Animator3
-keyset	create LS-DYNA keyword file "check-c.key" with *SET_xxx for penetrating nodes or elements - can be loaded into LS-PrePost or Animator3/4
-ani	create Animator session file for displaying nodes via "ide nod xxx"
-a4sel	create Animator4 session file for displaying nodes via "sel nod xxx" and create Animator4 groups named "id_"
-medina	create Medina protocol files
-mnode	node id for new node creation in Medina protocol (default=9.999.999)
-version	print version

Example:
% check13 -ptol=0.1 -ani -key -si 13,21 mes00*
