Definitions
Field | Contents | SI Unit Example |
---|---|---|
SID | Identification number of a
THIST entry. This does not need to be
unique. No default (Integer > 0) |
|
DTTH | Frequency of the time
history output.
Default = 100 (Integer > 0 or Real > 0.0) |
|
FILE | Suffix for the file name.
A maximum of 4 characters are allowed. This is beneficial with multiple THIST definitions, when specific results are desired in each file. By default, only one _TH.h5 file is generated. For example,
Default = blank (Character) |
|
LABEL | Label for the time history
file. No default (Character) |
|
ENTRY | Flag indicating that a
list of identifiers is following. Any number of entries can be
specified under the same THIST entry.
|
|
ID | Identifier for each
ENTRY. 4 (Integer > 0) |
|
CID | Output coordinate
system. This is only applicable for ENTRY = GRID and SHELL. Default = 0 (Global coordinate system) (Integer) |
|
VARi | Output data label. 4 No default (Character) |
Comments
- The THIST Bulk Data Entry must be referenced using the THIST Subcase Information Entry. It is only applicable for Explicit Dynamic Analysis (ANALYSIS = NLEXPL).
- The time history output is available in a _TH.h5 file HDF5 format file.
- If a THIST entry
has been referenced in the subcase, the global energy results are always
output by default. Even if FILE is defined, the global
energies are written only to the _TH.h5 file and not to
the other _TH<FILE>.h5 files. The global energies
are listed as follows:
- Output Data Label
- Description and Remarks
- IE
- Global internal energy.
- KE
- Global kinetic energy.
- CE_ELAST
- Elastic contact energy.
- CE_FRIC
- Frictional contact energy.
- HE
- Global hourglass energy.
- EFW
- Global external forces work.
- TE
- Energy sum = IE + KE.
- The following table summarizes the
ENTRY, ID and
VARi values for different output requests.Note: If VARi = ‘character prior to the parenthesis’, then all the results inside the parenthesis are output. For example, with ENTRY = SHELL.
- VARi = STRESS outputs time histories of F1, F2, F12, Q1, Q2, M1, M2 and M12.
- VARi = F1 only outputs time histories of F1.
