Hybrid and Conservative values

alvio

Hi, I have introduce new expressions to transform to tangential and radial velocity in CFX Post, but CFX do not let make made hybrid plots. Only Conservative ones are available. For Vtheta I defined as Vtheta= - Vx sen theta + Vy cos theta, where sen theta = x/(x^2+y^2)^0.5. The velocities I have used for the calculation are the ones in standard frame as I have multiple domains some of them rotating. Afterwards I defined the appropriated x and y components for Vtheta and Vr. Is there anyway to make hybrid choice available for the new variable? May it be that the expression that I have used gets undefined (for x=0 and/or y=0) and because of that it does not display the hybrid choice? Thanks, Alvio
