What Open Engineering does

Open Engineering is a Belgium-headquartered private software firm that develops and commercializes OOFELIE::Multiphysics, a HPC-ready multiphysics simulation platform used for structural, thermal, acoustic, electromagnetic, piezoelectric, and fluid–structure coupled analyses. The company serves mission-critical applications in defense, space, MEMS and transducers, optical systems (including STOP analysis), and semiconductor/electronics design, and positions its technology as a sovereign European alternative to foreign CAE stacks. The platform is built on a combination of FEM, BEM, FDTD, Fast Multipole Method, and Model Order Reduction techniques, with the OOFELIE::Multiphysics Solver as the computational core and OOFELIE::ADX for design-space exploration; the legacy OOFELIE::UI has been superseded by an integration into Siemens Simcenter 3D as the primary front-end.

The product surface is organized around a core solver and a set of vertical add-ons and integrations, including links to Siemens Simcenter 3D, Cadence Fidelity and FINE/Open with OpenLabs (for FSI), Zemax OpticStudio / RayJack ONE (for STOP analysis of optomechanical systems), SoftMEMS MEMS Pro (for the Tanner MEMS design flow), Microsoft Excel (for reduced-model simulation), and EDA simulators via VHDL-AMS and Verilog-A export. Open Engineering monetizes through one-time software licensing of the OOFELIE suite, professional services (multiphysics consulting, NX Open development, OOFELIE customization, and scientific code re-engineering), and training delivered on-site, at customer locations, or online. GTM is enterprise field sales via inquiry/trial request forms, supplemented by a network of Value Added Resellers across Belgium, France, Japan, Taiwan, Singapore, Korea, and North America, and co-marketing activity through the Skywin Cluster at events such as Paris Space Week and ESA/ESTEC Industry Space Days. The company is part of the GDTech group, has 11–50 employees, and has been operating since 2000 without disclosed external funding.

Core offering

Open Engineering develops and licenses the OOFELIE::Multiphysics Suite, a Belgium-developed HPC-ready multiphysics simulation platform for mission-critical defence, space, and industrial applications. The suite combines the OOFELIE::Multiphysics Solver (FEM/BEM/FDTD with coupled structural, thermal, acoustic, electromagnetic, piezoelectric and fluid-structure analyses) with the OOFELIE::ADX design space exploration tool, and integrates natively with Siemens Simcenter 3D, Cadence (FINE/Open, Fidelity), and Zemax OpticStudio. The company also delivers professional consulting, customization, and training services around the platform.

Product overview

Open Engineering develops and commercializes the OOFELIE::Multiphysics Suite, a sovereign multiphysics simulation platform built in Belgium. The suite consists of three major components: OOFELIE::UI (the parametric GUI, now superseded by Simcenter 3D integration), OOFELIE::Multiphysics Solver (the core computational engine), and OOFELIE::ADX (for design space exploration and optimization). The platform supports structural, thermal, acoustic, electromagnetic, piezoelectric, and fluid-structure coupled analyses. Open Engineering offers vertical applications for MEMS and transducers, optomechanical systems (STOP analysis with Zemax), and fluid-structure interaction (FSI coupling with Cadence FINE/Open). The solver integrates with Siemens Simcenter 3D as the primary interface, and also connects to Cadence products (Fidelity and FINE/Open), Zemax OpticStudio, SoftMEMS MEMS Pro, and EDA simulators via VHDL-AMS/Verilog-A export.

Broad incumbents

• Altair Engineering: Altair provides a broad CAE portfolio including HyperWorks for structural, thermal, and multiphysics simulation across aerospace, automotive, and industrial markets — competing with OOFELIE on integrated multiphysics engagements.
• ANSYS: ANSYS is the largest commercial CAE platform with broad multiphysics, structural, thermal, electromagnetic, and FSI capabilities across aerospace, defense, MEMS, and automotive. It competes with OOFELIE on enterprise multiphysics deals while offering a much wider product portfolio.
• Cadence Design Systems: Cadence is a core integration partner via Fidelity and FINE/Open (NUMECA) but also offers its own multiphysics and electromagnetic simulation flows targeting MEMS and semiconductor customers. It overlaps with OOFELIE in coupled electromagnetic-mechanical-thermal design for RF-MEMS and IC packaging.
• Siemens Simcenter (Siemens Digital Industries): Siemens Simcenter 3D is both Open Engineering's primary integration partner and a broad CAE incumbent with multiphysics capabilities. It overlaps directly in structural, thermal, vibro-acoustics, and piezoelectric workflows while controlling the front-end that OOFELIE now relies on.
• Dassault Systèmes SIMULIA: SIMULIA provides Abaqus-based structural and multiphysics simulation widely used in aerospace, defense, and automotive — competing with OOFELIE for the same European engineering customers on coupled structural, thermal, and FSI analyses.

Regional players

• ESI Group: ESI Group provides industrial virtual prototyping and multiphysics simulation focused on manufacturing, automotive, and aerospace — comparable to Open Engineering's industrial multiphysics positioning, with strong European heritage similar to OOFELIE's Belgian roots.

Emerging players

• Keysight Technologies (EMPro / PathWave): Keysight offers electromagnetic and RF simulation tools used in antenna, RCS, and high-frequency device design — overlapping with OOFELIE's FDTD-based high-frequency electromagnetics and recent RCS drone demonstration work.
• Dassault Systèmes CST Studio Suite: CST Studio Suite provides 3D electromagnetic simulation with FDTD and other solvers for antenna, RCS, and microwave device design. It competes directly with OOFELIE's high-frequency electromagnetics capability for defense and aerospace applications.

Others

• Zemax (Ansys Zemax OpticStudio): Zemax OpticStudio is Open Engineering's STOP-analysis integration partner for optomechanical systems. While primarily an optical design tool rather than a multiphysics competitor, it is highly comparable in workflows for MOEMS, deformable mirrors, and adaptive optics customers.

Direct peers

• COMSOL: COMSOL is the leading dedicated multiphysics simulation platform, offering strongly-coupled structural, thermal, electromagnetic, piezoelectric, and fluid-structure analysis modules. It directly competes with OOFELIE::Multiphysics across the same customer pain points and vertical applications.
