Temperatures

Note: Temperatures are only written in a thermal-only, combined structural and thermal, or structural analyses using thermal materials.

TEMPERATURE

Coordinates, velocities and accelerations are not written in a thermal-only analysis.

If "per surface" temperatures are present in the database, see below, then the simple TEMPERATURE data component reports the middle surface result.

Depending upon the value of THERM on the *DATABASE_EXTENT_BINARY card models may also contain:

TFX_TEMP_X_FLUX
TFY_TEMP_Y_FLUX
TFZ_TEMP_Z_FLUX

TFM_TEMP_FLUX_MAGNITUDE

TB_BOTTOM_TEMP
TM_MIDDLE_TEMP
TT_TOP_TEMP

These bottom, middle and top temperatures refer to the relevant surface of SHELL elements, but are written out at NODES . Nodes on solid elements have the same temperature value repeated at all three surfaces, the output for nodes on thick shell elements is not known at the time of writing.

Since these "per surface" temperatures are nodal data, and also since shell output may be present in the database for some number other than these 3 surfaces (see MAXINT on *DATABASE_EXTENT_BINARY) it would be misleading to use the normal "shell surface" selection method since that could imply that temperatures are available at all integration points. Therefore these are treated as unrelated nodal quantities, and in order to see temperatures at a given shell surface it is necessary to select the relevant component explicitly.

If flag DTDT on *DATABASE_EXTENT_BINARY is set then the following temperature component will be output

TR_TEMP_RATE

The rate of change of temperature, dTemp/dTime.

Other nodal data
If MSSCL on *DATABASE_EXTENT_BINARY is set:
MASS_SCALING	Either incremental or %age change of nodal mass. (There is no way to tell which it is from the information in the database file, you will have to interpret it correctly.)
