chenu New Member chen yu Huang Join Date: Nov 2019 Posts: 18 Rep Power: 7	Hello, I have a question about solving velocity. In the icoFOAM velocity is first evaluated by UEqn.solve(), then in the PISO loop the "corrected" velocity is derived by HbyA. From the discretized equation of HbyA we know it is velocity.My question is: what is the different between UEqn.solver() and HbyA? Could I use HbyA instead of UEqn.solve() to derive velocity. Thank you.
