modeFRONTIER vs OpenPISCO

modeFRONTIER automates engineering simulation workflows and design optimisation by connecting third-party CAD/CAE software with in-house solvers. It combines multiple engineering disciplines in unified workflows and allows several optimisation strategies in one project file. Design exploration includes design of experiments, response surface models, multi-objective optimisation, robust design, reliability analysis and uncertainty quantification. Surrogate models, machine-learning algorithms and reduced-order models support data-driven modelling; ESTECO identifies pilOPT as its proprietary self-adaptive optimisation algorithm. Integrations include parametric solvers and custom connectors for Abaqus, Adams, ANSYS Workbench, CATIA and ANSA. pyFRONTIER and pyCONSOLE connect Python workflows, including scikit-learn and SciPy optimize libraries. Workflows can run in parallel, on local grid computing, or through remote HPC and cloud resources. VOLTA adds collaboration, distributed execution and result traceability. Pricing is on request, with academic licences limited to non-commercial or academic use.

OpenPisco is an open source research and development platform for topology optimization using the level-set method. It combines optimization algorithms, direct and adjoint analyses, remeshing tools and level-set algorithms, with methods for fixed-mesh shape capturing and body-fitted mesh shape tracking. The design process supports grids, unstructured meshes and body-fitted meshes, and includes an interface to MMG3D for remeshing. Users can work through a Python library and API, the OpenPiscoCL command-line application, or a graphical application. The Python interface targets developers and advanced users; the command line supports automation, batch processing and HPC execution, while the GUI is suited to visualization. Plugins allow custom mesh readers, optimization algorithms and physics solvers to be added without changing existing source code. Documented external solver options include Code_Aster, FreeFem, ZSet and OpenFOAM; an internal finite element solver is also available. Built on the Muscat library, OpenPisco is intended for industrial and academic research, including rapid prototyping of topology optimization methods. Documentation reports installation on Ubuntu Linux, macOS, Windows 10 and WSL 20.04.
