Temperature

PROPERTY LOAD TEMPERAT [load_name] [loadcase_no] part_name/ALL args

Argument Meaning

load_name FEMGEN load name (can also be the name of a DPL file, see note 5).

loadcase_no FEMGEN loadcase number (links load to an ANSYS step).

part_name Any geometry containing nodes.

arg1 Temperature value (or 1 for a DPL file).

arg2 Indicator used only for thermal constraints, set to 1

Notes:

1.

The interface will apply the same temperature value to all nodes attached to the specified geometry.

2.

If arg1 only is defined (arg2=0) then ANSYS structural temperature body load is generated.

3.

If arg2 is set to 1 then ANSYS constraint with a thermal degree of freedom, TEMP, is generated.

4.

Prescribed temperatures and more general prescribed values can be defined with the FEMGEN command 'PROPERTY BOUNDARY PRESCRIBE', see above.

5.

If the load name starts with 'TEMP' then the interface program treats it as being the name of a DPL (Discrete Point Load) file that contains the temperature values at the nodes.

• It is assumed that the points in the DPL file match the nodes of the current mesh. Note that a simple proximity criterion is used: the value at the nearest point to the node is attributed to this node.
• A valid part is either a surface, a set of surfaces or 'All' when the whole model only contains surfaces. In all cases surfaces must be meshed with shell elements only.
• Neither arg1 or arg2 are used, however arg1 needs to be entered.
• Load masks and space curves are supported.
• The DPL file must contain 4 columns of real numbers written in free format; the first three columns are for the nodes global coordinates and the last column gives the temperature value.
• The DPL file is expected to be either in the current working directory or in the directory specified by the environment variable FG_ANS_DPL, see paragraph 1.4 of Chapter 1.
