Computational time (s) versus number of finite-elements for CSMP++ and other solvers in ANSYS software package: Fluent-Simple, CFX-15, CFX4.3 and Fluent-NITA simulations. Numerical simulations were carried out using different computing system specifications. IBM RS/6000 workstation with Power 3 II processor was used for CFX4.3 simulation; 3.2 GHZ Intel i7 processor with 32 GB RAM and 4 cores was used for Fluent-Simple, CFX-15 and Fluent-NITA; Intel core v5.1, CPU 3.20GHz, and 8 GB memory, with 4 cores was used for CSMP++ simulations. Computation becomes prohibitively expensive as the number of elements increases in ANSYS Fluent simulation.
