ANSYS Geometry Inter­face: Fast and Easy Automation

The CAESES ACT app is an ANSYS geometry inter­face by FRIEND­SHIP SYSTEMS that allows CFD engi­neers to automate the entire geometry gen­er­a­tion process, for the purpose of running shape opti­miza­tion and design studies.

With the ACT app, new design variants are created with a single click in the back­ground of the ANSYS GUI, and the new geometry is trans­ferred to the Work­bench without any manual user inter­ac­tion. These exter­nally created geometry can­di­dates can be auto­mat­i­cally meshed and analyzed with all the ANSYS tools, which is the pre­req­ui­site for CFD-driven studies.

ANSYS Geometry Inter­face: Video

We prepared a short video that demon­strates how easy it is to connect CAESES to the ANSYS Work­bench. As an example, a para­met­ric pump impeller is given in CAESES. The geometry setup contains a set of design vari­ables that controls the shape mod­i­fi­ca­tions. A ded­i­cated Tur­bo­Grid feature of CAESES then exports the geometry using the Tur­bo­Grid format. By running CAESES in batch mode, the entire geometry gen­er­a­tion is auto­mated without any script­ing efforts by the ANSYS user. 

Benefits of the CAESES-ANSYS Coupling

Compared to the use of tra­di­tional CAD tools, the main benefits of this CAESES-ANSYS geometry inter­face are the robust variant gen­er­a­tion (no failed designs during the process) and a para­me­ter-reduced, highly effi­cient CAD model (less com­pu­ta­tions). Since CAESES is a gen­er­al­ized CAD solution for shape opti­miza­tion with sim­u­la­tion tools, any appli­ca­tion from any industry can be con­sid­ered. In par­tic­u­lar, CAESES focuses on complex free-form shapes and their clever para­me­ter­i­za­tion. The ACT app makes sure that the Named Selec­tions of ANSYS are fixed and do not change, to be able to record and replay every­thing during auto­mated studies.
