A discipline for topology optimization volume fraction.

class VolumeFraction(n_x=100, n_y=100, empty_elements=None, full_elements=None, name='')[source]#

Bases: Discipline

Compute the volume fraction from the density.

Volume fraction is computed as the average of the density value (rho) on each finite element.

Initialize self. See help(type(self)) for accurate signature.

Parameters:

  • n_x (int) --

    The number of elements in the x-direction.

    By default it is set to 100.

  • n_y (int) --

    The number of elements in the y-direction.

    By default it is set to 100.

  • empty_elements (Sequence[int] | None) -- The index of the empty element ids that are not part of the design space.

  • full_elements (Sequence[int] | None) -- The index of the full element ids that are not part of the design space.

  • name (str) --

    The name of the discipline. If empty, use the name of the class.

    By default it is set to "".
