# 7.6.3.5.3. 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 where is the volumetric expansion coefficient and is the stress tensor. This model uses the mesh stress provided by a projection equation in order to recover stress gradients.
