CAESES is a software solution designed for simulation engineers to optimize the design of fluid flow systems. With a focus on simulation-driven design, CAESES offers specialized tools for the parametric modeling and shape optimization of complex geometries, such as those found in ship hulls, turbomachinery, and automotive components. This software integrates with various computational fluid dynamics (CFD) and finite element analysis (FEA) tools, allowing users to enhance performance and efficiency through automated workflows. CAESES emphasizes the reduction of simulation iteration times and supports the creation of high-quality design spaces for improved product development.
