Grid Point Temperature Field Default
Description: Defines a temperature value for all grid points of the structural model that has not been given a temperature on a TEMP entry.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| SIDi | Temperature set identification number. | Integer > 0 | Required |
| Ti | Temperature value. | Real | Required |
Remarks:
- SIDi must be unique with respect to all other LOAD type entries.
- From one to four grid point temperatures may be defined on a single entry.
- If thermal effects are requested, all elements must have a temperature field defined either directly on a TEMPP1 or TEMPRB entry, or indirectly as the average of the connected grid point temperatures defined on the TEMP or TEMPD entries. Directly defined element temperatures always take precedence over the average of grid point temperatures.
- Grid point temperatures are obtained by averaging element temperatures at the grid point. If no element temperature is specified then the temperature defined by the above entry is used.
- Equivalent grid point loads are computed by numerical integration using isoparametric shape functions. Note that a uniform temperature will not necessarily result in equivalent grid point loads.
