Backward Compatibility with Version 5.1

Changes in Variable Names

The names of the heat capacity variables have changed in several features for consistency:

•	In the Bioheat feature, ht.cb has become ht.cp_b.

•	In the Thin Layer feature, ht.cs has become ht.cp_s.

•	In the Thin Rod feature, ht.cl has become ht.cp_l.

•	In the Thin Layered Shell feature, htsh.cs1 has become htsh.cp_s1, and so on.

•	In the Heat Transfer in Porous Media feature, ht.c_pp has become ht.cp_p, ht.c_pp1 has become ht.cp_p1, and so on.

•	In the Immobile Fluids feature, ht.c_pg1 has become ht.cp_g1, and so on.

•	In the Fracture feature, ht.c_pfr has become ht.cp_fr.

The names of the thermal resistance and absolute thermal resistance variables have changed in the Isothermal Domain Interface feature:

•	ht.idi1.Rs has become ht.idi1.R_t

•	ht.idi1.Rsth has become ht.idi1.R_tth

The name of the fluid viscosity variable has changed in the Local Thermal Non-Equilibrium multiphysics coupling: ltne1.mu_f has become ltne1.mu.
