Axisymmetric2D3DSolutionFunction

Function for reading a 2D axisymmetric solution from file and mapping it to a 3D Cartesian model

The 2D solution is likely to be the output of a 2D-RZ calculation, which we want to compare to a full 3D model. This is useful for assessing the validity of the 2D-RZ geometric approximation.

The axis of symmetry for the original 2D axisymmetric calculation and for mapping this 2D axisymmetric calculation into the 3D space can both be specified.

Example input syntax

In this example, three Axisymmetric2D3DSolutionFunction are used to load results for a 2D axisymmetric simulation in a 3D mechanics simulation. These results are then used in the BCs block to impose a displacement on a boundary, and in a temperature variable using a FunctionAux.
