Diffusion term in the conservation equation of species

[wengzf20]

The conservation equation of species in the user guide, i.e. $\frac{\partial \rho Y{s}}{\partial t} + \nabla \cdot(\rho Y{s} \mathbf{u}) = \dot{R}{s}$, does not have the diffusion term. The diffusion term ($\nabla \cdot(\rho Y{s} \mathbf{u}{d,s})$) should be added in the left hand side of the equation. However, this term is included in the source `fvScalarMatrix YiEqn ( fvm::ddt(rho, Yi)

• fvc::ddt(rho_, Yi)

• thermophysicalTransport_->divj(Yi)

              reaction_->R(Yi)

• modelsPtr_->source(Yi) );` Is it a typo in the user guide?

Hello, It is a typo that it is missing in the User Guide. Thank you for pointing that out. It will be added next time we have a release.

OK. Thank you.
