FENSAP-ICE-TURBO is the 3D turbomachinery module that fully integrates the capabilities of FENSAP-TURBO, CFX, DROP3D-TURBO, ICE3D-TURBO and C3D/CHT3D-TURBO to compute the steady-state airflow, droplet/ice crystal impingement and ice accretion solutions in multistage turbomachinery components. Each component is solved independently, and the interaction between components is updated at every iteration using interfaces. The use of mixing planes to transfer boundary conditions at the interfaces provides the flexibility to handle multi-component grids with non-matching nodes, as well as unequal pitch.
