model.shape(<tag>) returns a shape function.
model.shape().create(<tag>,<frame>) creates a shape function with tag
<tag> and assigns the frame
<frame> to it.
model.shape(<tag>).frame(<ftag>) assigns frame
<ftag> to the shape function. See
model.frame() for a discussion on the default frame.
model.shape(<tag>).create(<ftag>,<func>) creates a shape feature with the shape function expression
func.
func can be a shape function name (
shlag, for example) or a shape function with arguments (
shlag(2,u), for example). The latter is interpreted as an assignment of some property values.
model.shape(<tag>).feature(<ftag>).set(property,<value>) sets a property for the shape function. Of the data types listed in
Table 2-2, the ones supported are those for integers, strings, and string arrays. Which ones are applicable differs for each property.
model.shape(<tag>).selection().named(<seltag>) assigns the shape function to the named selection
<seltag>.
model.shape(<tag>).selection().set(...) defines a local selection that assigns the shape function to geometric entities. For a complete list of methods available under
selection(), see
Selections.
model.shape(<tag>).upFlux(<varName>) and
model.shape(<tag>).downFlux(<varName>) set the names of the up and down boundary flux variables.
model.shape(<tag>).domainFlux(<expressions>,<frame>) sets expressions for the domain flux in a given frame. This is required to make the boundary flux variables produce accurate results. Only Lagrange shape functions support boundary flux variables.
model.shape(<tag>).frame() returns the frame tag as a string.
model.shape(<tag>).feature(<ftag>).shape() returns the shape function expression as a string.
model.shape(<tag>).feature(<ftag>).getType(property) returns a property value. For available data types, see
get* and Selection Access Methods.
model.shape(<tag>).feature(<ftag>).properties() returns the names of the properties as a string array.
model.shape(<tag>).fieldVariable() returns the field variables which the shape functions define.
model.shape(<tag>).selection().named() returns the selection tag as a string.
model.shape(<tag>).elementSet(<condition>) sets the element set condition to the given string. The condition should be an expression containing
element set variables (defined in
model.elementSet()) and the logical operators
&&,
||, and
!. The shape function is defined only on the mesh elements for which the condition is true (nonzero).
model.shape(<tag>).elementSet() returns the element set condition. An empty string means no condition.
model.shape(<tag>).selection().getType() returns domain information. For available methods, see
model.selection().
model.shape(<tag>).slits() returns a selection used to generate a slit on the shape. Works exactly as selections.
model.shape(<tag>).upFlux() and
model.shape(<tag>).downFlux() return the names of the up and down flux variables (an empty string if the variable names have not been set.)
