DerivedSubfieldsElasticity

Full name:

pylith.materials.DerivedSubfieldsElasticity

Journal name:

derivedsubfieldselasticity

Derived subfields associated with the elasticity equation.

For elastic materials these derived subfields are available for output in addition to the solution and auxiliary subfields.

Pyre Facilities

• cauchy_strain: Cauchy strain subfield.

  • current value: ‘subfield’, from {default}

  • configurable as: subfield, cauchy_strain

• cauchy_stress: Cauchy stress subfield.

  • current value: ‘subfield’, from {default}

  • configurable as: subfield, cauchy_stress

Example

Example of setting DerivedSubfieldsElasticity Pyre properties and facilities in a parameter file.

# The basis order for stress and strain should be at least 1 less than the basis order for displacement.
[pylithapp.problem.materials.mat_elastic.derived_subfields]
cauchy_stress.basis_order = 0
cauchy_strain.basis_order = 0
