Real Time Simulation

Most CFD calculations we find for industrial applications, use Steady-State methods. For a Steady-State-Solver the concept of physical time is meaningless. This approach is used because of the lower computational cost; and for many problems Steady-State calculations offer a cost-effective solutions. However, all flows in nature are transient, i.e. non-steady! For many applications a steady-state solution is insufficient and transient or time-dependent analysis are required, such as:


 Study of mixing time in a stirred reactor: With time dependent unsteady analysis it is possible to accurately determine the time required for a mixer to homogenize a liquid medium.
