Additional physicality constraints to attempt to prevent non-physical flow parameters from occurring. Instead of checking if the solver parameters are non-physical, we will check if some solver parameters decrease by a certain fraction and apply some damping if the fractional decrease is too great. This method slow the flow solve a bit if not needed.

pcality% on
Description: Turn on extra physicality checking? Parameter Type: logical
pcality% maxits
Description: Maximum allowable attempts to damp the solution update. If the maximum number of iterations is met and the flow variables are physical but do not meet the imposed physicality constraints, the flow solve continues anyways. Parameter Type: Integer Range of Acceptable values: [1,inf]
pcality% damp
Description: Damping factor to apply if the physicality constraints are not met Parameter Type: real Range of Acceptable values: (0,1)
pcality% rho_mafd
Description: Maximum allowable fractional decrease in density per solution update, checked element-wise Parameter Type: real Range of Acceptable values: Usually (0.1,0.2)
pcality% e_mafd
Description: Maximum allowable fractional decrease in energy per solution update, checked element-wise Parameter Type: real Range of Acceptable values: Usually (0.1,0.2)
