---|---|---|
SID | LOAD set identification.
(Integer > 0) |
|
G/GSETID | This field represents a
Grid point identification number, or if the GSET
continuation line is specified, an identification number of a SET of
grid points. (Integer > 0) |
|
Ti | Temperature at
ith layer. (Real) |
|
GSET | Flag to indicate that the G/GSETID field is identified as a SET of grid points at which the temperatures are applied. |
Comments
- TEMPSEC is supported only for grids associated with shell elements. It is supported in implicit nonlinear static analysis and implicit nonlinear transient analysis. Both small and large displacement nonlinear analysis are supported.
- The TEMPSEC entry is available to define the
through-thickness temperature field as defined below:
- Temperature sets may be selected for use in an implicit nonlinear subcase by the TEMPERATURE(LOAD) or TEMPERATURE(INITIAL) Subcase Information Entry.
- They can also be selected by the EXCITEID field of a TLOAD# entry. In this case, all the temperature values on the individual shell grids vary as defined by the curve on the corresponding TLOAD#.
- They can share the same ID with TEMP and/or TEMPD Bulk Data.
- They can also be combined with other TEMP or TEMPD Bulk Data on a TEMPADD Bulk Data Entry. For more information, refer to the TEMPERATURE Subcase Information Entry.
- When multiple temperature values are defined for one grid, the temperature values are assigned to layers which are equally distributed through shell thickness direction from bottom to top.
- Temperature-dependent material and thermal strain are evaluated at each layer of shell elements as per the temperature definition defined at each section.
- The TEMPP1 entry is similar to the
TEMPSEC entry, with the following differences:
- For TEMPP1, the temperatures are defined at each element, while for TEMPSEC the temperature values are defined at each grid.
- For TEMPP1, the temperatures over thickness direction is linearly distributed, while for TEMPSEC, the temperatures over thickness are distributed in a piecewise linear manner.
