TOPT  is  a software module for  parametric optimization based on simulation results. TOPT works best inside the simulation environment TCAE. TCAE consists of modules TCADTMESHTCFDTFEA, and TOPT.

TOPT enables solving a wide range of optimization tasks. Based on the simulation results (optimization function), TOPT can optimize parameters for model shapes, flow velocity, various boundary conditions, or any other model parameters or simulation setup. The optimization function can be based, for example, on the model efficiency, material stress, best RPM, flow coefficients, or on any other simulation results.

Example 1: Shape Optimization

TOPT is used inside the simulation environment TCAE. The TOPT running mode can be either “DOE” (Design Of Experiment) or “optimize”. Mode DOE can be either explicit or implicit. Mode optimize can be either external or built-in. TOPT running loop can easily include external software for CAD model creation, or for parametric space transformation, or optimization. All the external software pieces can be added to the TOPT work scheme. TOPT is flexible enough to work with in-house codes, commercial codes, and open-source. The following scheme shows how TOPT works.

Example 2: Finding Best Parameters

TOPT Airfoil NACA 2412 Best Cl CFD Optimization 1.5

TOPT can find the highest value of the optimization function. In this example, the optimization function is the lift coefficient of an Airfoil NACA 2412. The main parameter is the angle of attack. TOPT runs an optimization loop to find the highest lift coefficient depending on the flow angle of attack.

Example 3: Complex Turbomachinery Optimization

TOPT can be used for very complex optimization workflows to deliver the winning design with the best possible performance.  In this example, the whole centrifugal fan was optimized. Five parameters were variable to follow the efficiency as an optimization function.
