The parameters in the Abortion tab define convergence criteria and underrelaxation when solving buoyancy driven convection, i.e. when Navier-Stokes- and Temperature-equation have to be solved.

Inner iteration limits

Momentum 1 and Temperature 1 are convergence criteria for inner iteration loops.

Stop of computation

The computation shall stop when both specified values, Momentum 2 and Temperature 2 are reached or the solution is no longer changing (max. solution change).

with buoyancy

Buoyancy driven convection is solved (default).

Underrelaxation velocity factors

You can specify a linear dependency of the underrelaxation factors for the velocity equation.
