I have a problem.......... I would like to set in the Advection scheme of the solver (in CFX-Build) to 2th order, specifing the blend factor = 1. , but when i select the blend factor i can't set up the order of the examination. How does it works?

thanks

you can not set both schems. if you choose a second order then you can not specify blend. if you set a blend factor on 0.5 it is eqal to second order. blend can be set between 0 and 1 but you must be carefull because with increasing bled roboustness decreases. for most engineerig problems blend of 0.75 is ok bu it is better to start the calculation with smaller blend and increase it later.
