gamma_h

module opensg.utils.shell

opensg.utils.shell.gamma_h(e, x, w)

Compute the gamma_h operator for MSG-Shell formulations.

This function computes the gamma_h operator. It represents the strain measures in terms of the displacement field.

Parameters:

• e (tuple) – Local frame vectors (e1, e2, e3)

• x (ufl.SpatialCoordinate) – Spatial coordinates

• w (ufl.Coefficient) – Test or trial function

Returns:

ufl.Tensor – 6-component vector representing the strain measures
