seghandle
Listing and manipulation of interface segment files.
Seghandle allows users to list and manipulate binary interface segment files which are created by LS-DYNA option *INTERFACE_COMPONENT_xxx.
If none of the manipulation options is chosen then seghandle just lists each time step with min/max coordinates and rotations of all nodes. Additionally it gives a summary of the number of interfaces, nodes, states and scale factor for the file family. The summary is saved to a file named "seghandle.prot".
The manipulation options allow scaling of the displacements, offsetting the time points, changing (reduce only) the time/state intervall, skipping the rotations and changing the file size scale factor.
| usage: | seghandle segment-file [options] |
segmentfile should have been created by LS-DYNA via z=file
options:
| -bs | try to read in byteswap format |
| -tx tintervall | time extraction interval for output |
| -sx intervall | state extraction interval for output |
| -dt toffset | time offset value |
| -ds fac | displacement scale factor |
| -xs fac | x-displacement scale factor |
| -ys fac | y-displacement scale factor |
| -zs fac | z-displacement scale factor |
| -o file | output filename (default="scl_" |
| -x fac | LS-DYNA file size scale factor (default 99) |
| -norot | no nodal rotational data in output |
| -quiet | no min-max info written each state |
| -key | write geometry in LS-DYNA keyword format - nodes per interface on a separate file named "interfaceX.key" |
| -keyall | write geometry in LS-DYNA keyword format - all nodes in one file named "interface.key" |
| -plot | converts all data into d3plot-format file default name: "segplot", use -g to change name |
| -g | optional filename for d3plot-format file |
| -sp states | number of states per plotfile (output) default: all states in one file |
| -v | gives version number |
| -h | give this help on screen |
