Case Study: Engrana reduces geometry-prep time by 50% and accelerates CFD optimization with ANSYS (SpaceClaim)

Engrana Utilizes SpaceClaim in CFD Analysis

Engrana, a CFD and thermal-analysis consulting firm, faced the recurring challenge of preparing customer-supplied CAD geometries that were over-detailed or dirty for flow analysis and high-quality meshing. To address this, Engrana adopted SpaceClaim within the ANSYS ecosystem and runs simulations with ANSYS FLUENT as part of its analysis toolchain.

By using the ANSYS-integrated SpaceClaim, Engrana streamlines de-featuring, geometry simplification, flow-volume extraction, and geometry decomposition for hex-dominant meshes, and easily parametrizes design variants for optimization. This solution eliminated time-consuming iteration loops with clients, became Engrana’s primary preprocessor, and delivered measurable impact—reducing geometry-prep time by at least 50% while feeding directly into ANSYS FLUENT simulations.
