Free [Download](/app/phimeca/flatness-defect/1-1/download-app) ## App Description This app evaluates the flatness of any surface of your geometry selected in Ansys Mechanical. It computes the coefficients of the plane and displays its 3D graphical representation. To compute the plane, the app applies the least square method to the displacement results from the chosen surface. By providing the maximum and minimum distances between surface nodes and the computed plane, this app facilitates a thorough understanding of the computed value for the surface's flatness. ## Key Benefits Avoid the laborious task of manually computing flatness defects in tools like Excel. This app automates this process entirely within Ansys Mechanical, saving you valuable time and effort. ## Images ![FlatnessDefect](/sites/default/files/2025-05/001_FD_1.1_Flatness%20Defect_1.png "Flatness Defect") Flatness Defect ## Latest version Flatness Defect 1.1 Supported Ansys versions: 2017 R1 [Download](/app/phimeca/flatness-defect/1-1/download-app) Go to top Publisher![Publisher logo](/sites/default/files/2025-05/LogoPhiHaut.png) PHIMECA Support information Zénith Business Center, 34 rue de Sarliève, F-63800 Cournon d'Auvergne France +33 4 73 28 93 66
