INTERPRETING PDE COEFFICIENTS
The PDE formulations in COMSOL Multiphysicscan model a variety of problems, but this guide, as well as
the interface, uses descriptive names for the coefficients that fall within the realm of continuum mechanics
and mass transfer. For the coefficient form PDE:
 ea is the mass coefficient.
 da is a damping coefficient or mass coefficient.
 c is the diffusion coefficient.
 留 is the conservative flux convection coefficient.
 硫 is the convection coefficient.
 a is the absorption coefficient.
 粒 is the conservative flux source term.
 f is the source term.
