Scriptable pipeline for computing friction forces within a circular and an arbitrarily-shaped plane-stress shafts for the demonstration of the applicability of AI in design optimization. The FEA tool-chain is based on Gmsh and Fino, takes an STL with the shape of the external shaft, reparametrizes and meshes it, solves the penetration problem with an iterative scheme and computes the frictional force as the integral of the normal stresses over the contact area.

Estimation of fatigue lifetime resistance of custom-designed hip implants in titanium and high-alloy stainless steels according to ISO requirements. Verification and validation of the FEA tool-chain (based on Gmsh and Fino), convergence analysis of the meshing scheme and fitting of S-N curves to experimental data.

A pipeline for unattended (i.e. non-GUI) computation of mechanical stresses in tailor-made hip implants was needed. Seamplex designed and implemented a tool to perform the required finite-element analysis using Fino in a totally automated way. The tool, a main Bash script that called Python and M4 for other particular tasks following the UNIX philosophy, assembles the parts into a single CAD using OpenCASCADE (through the Gmsh wrapper), meshes the assembly, solves the linear elastic problem and creates a JSON file with the main results and a detailed VTK file with the displacement and stress distribution. A full set of test and documentation was included, including building instructionss, Software Requirement Specifications and Software Design Specifications.
