Definitions
Field | Contents | SI Unit Example |
---|---|---|
SID | THIST
entry identifier number. 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) |
|
CSURF | Flag to indicate output of surface-based data. | |
SRFID | Surface identifier. This is valid only for surface-based data format. No default (Integer > 0) |
|
CID | Output coordinate
system. This is only applicable for ENTRY = GRID and SHELL. Default = 0 (Basic 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:
- 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
- PE
- Global plastic dissipation 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:
- In the below table, if VARi = {character
prior to the parentheses}, then all the results inside the
parenthesis are output. For example, with
ENTRY = SHELL
- VARi = STRESS outputs time histories of SX1, SY1, SXY1, SX2, SY2, and SXY2.
- VARi = SX1 only outputs time histories of SX1.
- VARi = ALL or blank are supported for all entries and this outputs the result for all the components of an output data label.
