ABC for Auxetic Unit Cells

class pyauxetic.classes.auxetic_unit_cell.AuxeticUnitCell(model, params)

Abstract base class for defining an auxetic unit cell. It defines the core behavior and must be subclassed for different unit cells.

__init__(model, params)

Initialize the unit cell with the given parameters.

Child classes must first define self.name and afterwards call this function using super(ChildClass, self).__init__(params). This function then creates the self.sketch and self.part_main.

Logging is done in the child classes.

Parameters:

• model (Model) – Abaqus Model object in which the unit cell will be created.

• params – Parameters describing the unit cell geometry. See child classes for valid object types.

property part_3dprint

Abaqus Part object suitable for 3D export. If the part does not exist, it will be created.

property part_main

The main Abaqus Part of the structure which can be planar or 3D. If the part does not exist, it will be created.

abstract create_sketch()

Create the 2D sketch for the unit cell. See child classes for implementation.

abstract create_part_main()

Create the main part of the unit cell based on the sketch. See child classes for implementation.

abstract create_part_3dprint()

Create the part used for 3D printng based on the sketch. See child classes for implementation.
