7.6.3.4.3. Isotropic_Mesh_Stress

Syntax: Chemical Potential [{of} SpeciesName] = Isotropic_Mesh_Stress Strain_Coeff = strain_coeff
Scope: Aria Material
Summary: Contribution to the chemical potential from species strain. Assumes that the strain is isotropic so $\mu = \Omega \sigma_{kk}/3$ where $\Omega$ is the volumetric expansion coefficient and $\sigma$ is the stress tensor. This model uses the mesh stress provided by a projection equation in order to recover stress gradients.
