Hello, everyone!

I was looking at the differences between laminar and turbulent modeling of a case (multiphaseEulerFoam > RAS > bubbleColumn) and I realized that one of the divergence scheme is different for laminar and RAS case. Is this a typo or am I missing something?

"div\(\(\(\(alpha.*\*thermo:rho.*\)\*nuEff.*\)\*dev2\(T\(grad\(U.*\)\)\)\)\)" Gauss linear;
--> laminar

"div\(\(\(\(alpha.*\*thermo:rho.*\)*nuEff.*\)\*dev2\(T\(grad\(U.*\)\)\)\)\)" Gauss linear;
--> RAS

The difference is " )\*nuEff. " parts of both lines. The laminar case has \ but RAS is missing it.

Thank you in advance,
