Loading

Finite Element Loads

This module provides functions for creating loads.

Notes

These functions are useful for defining loads and subdomains in finite element simulations.

Examples

See individual function documentation for usage examples.

phasefieldx.Loading.loading_functions.loading_Tx(msh, value=0.0)

Create a constant scalar load (e.g., traction or body force) in the x-direction.

Parameters:

mshdolfinx.mesh.Mesh

The computational mesh.

valuefloat, optional

The value of the load in the x-direction (default is 0.0).

Returns:

dolfinx.fem.Constant

A constant scalar value for use in variational forms.

Notes

This function is useful for defining constant scalar loads in 1D or as a component in higher dimensions.

phasefieldx.Loading.loading_functions.loading_Txy(msh, value_x=0.0, value_y=0.0)

Create a constant vector load (e.g., traction or body force) in 2D.

Parameters:

mshdolfinx.mesh.Mesh

The computational mesh.

value_xfloat, optional

The value of the load in the x-direction (default is 0.0).

value_yfloat, optional

The value of the load in the y-direction (default is 0.0).

Returns:

dolfinx.fem.Constant

A constant 2D vector for use in variational forms.

Notes

This function is useful for defining constant vector loads in 2D finite element simulations.

phasefieldx.Loading.loading_functions.loading_Txyz(msh, value_x=0.0, value_y=0.0, value_z=0.0)

Create a constant vector load (e.g., traction or body force) in 3D.

Parameters:

mshdolfinx.mesh.Mesh

The computational mesh.

value_xfloat, optional

The value of the load in the x-direction (default is 0.0).

value_yfloat, optional

The value of the load in the y-direction (default is 0.0).

value_zfloat, optional

The value of the load in the z-direction (default is 0.0).

Returns:

dolfinx.fem.Constant

A constant 3D vector for use in variational forms.

Notes

This function is useful for defining constant vector loads in 3D finite element simulations.
