chemtech Introduction I VIII International Phoenics Users Conference Special purpose tools for performing series of simulations of specific equipment Builds error free Q1 files based in equipment engineering inputs Controls access to PHOENICS modules Allows saving and reloading cases without loosing original input

chemtech Introduction II VIII International Phoenics Users Conference Why develop a system like that ? The system allows industrial equipment designers, whithout time to invest in learning CFD, take full advantages of the benefits of PHOENICS Different data inputs boundary conditions fluid properties object positions numerical settings grid operational conditions equipment geometry With the HMIWithout the HMI
