assign_hollow_block#
- Icepak.assign_hollow_block(object_name, assignment_type, assignment_value, boundary_name=None, external_temperature='AmbientTemp')[source]#
Assign block boundary for hollow objects.
- Parameters:
- object_name
str
orlist
Object name or a list of object names.
- assignment_type
str
Type of the boundary assignment. Options are
"Heat Transfer Coefficient"
,"Heat Flux"
,"Temperature"
, and"Total Power"
.- assignment_value
str
ordict
String with value and units of the assignment. If
"Total Power"
is the assignment type,"Joule Heating"
can be used. For a temperature-dependent or transient assignment, a dictionary can be used. The dictionary should contain three keys:"Type"
,"Function"
, and"Values"
. - For the"Type"
key, accepted values are"Temp Dep"
and"Transient"
. - For the"Function"
key, acceptable values depend on the"Type"
key selection. When the"Type"
key is set to"Temp Dep"
, the only accepted value is"Piecewise Linear"
. When the"Type"
key is set to"Transient"
, acceptable values are “Exponential”`, “Linear”`,"Piecewise Linear"
,"Power Law"
,"Sinusoidal"
, and"Square Wave"
. - For the"Values"
key, a list of strings contain the parameters required by the"Function"
key selection. For example, when``”Linear”`` is set as the"Function"
key, two parameters are required: the value of the variable at t=0 and the slope of the line. For the parameters required by each"Function"
key selection, see the Icepak documentation. The parameters must contain the units where needed.- boundary_name
str
,optional
Name of the source boundary. The default is
None
, in which case the boundary is automatically generated.- external_temperature
str
,dict
orfloat
,optional
String with the value and unit of the temperature for the heat transfer coefficient. If a float value is specified, the
"cel"
unit is automatically added. For a transient assignment, a dictionary can be used as described for theassignment_value
argument. Temperature dependent assignment is not supported. The default is"AmbientTemp"
.
- object_name
- Returns:
pyaedt.modules.Boundary.BoundaryObject
Boundary object when successful or
None
when failed.
