The legacy OTOM desktop tools (AFP Engine, AFP Viewer and Ray-tracer) are no longer supported as of 2025. Their functionality continues in AFP Web.
OTOM, Optimizing Thermo Optical Modeling is a physics-based CAE software for the automated fiber placement process. It accurately selects and controls hundreds of AFP process parameters to deliver a robust, tailored product, and can interact with the PLC to increase your productivity.
OTOM AFP Web
AFP Web is the online edition of the OTOM AFP simulation suite — the same physics-based models that run in our desktop software, delivered straight in your browser. There is nothing to install and nothing to maintain: open the link, set up your lay-up, and read the results.
- Kinematics — path definition, laser head position, tilt and yaw for the placement or winding process.
- Optical — ray tracing of the laser beam, including the reflection pattern driven by fiber orientation.
- Thermal — nip-point and through-thickness temperature history of tape and substrate.
- Crystallinity — degree of crystallinity derived from the simulated thermal history of thermoplastics such as PEEK, PEKK and PPS.
- IR — a thermal-camera view of the process, so simulation and measurement can be compared side by side.

OTOM CFD
OTOM CFD is a real-time computational fluid dynamics solver that runs on the GPU in your browser through WebGPU. Change the geometry, the inlet or the angle of attack and the flow answers at once, so design questions that used to wait overnight can be explored in a meeting.
- Incompressible engine — Chorin projection method with a pressure Poisson solve, Smagorinsky LES turbulence and vorticity confinement.
- Compressible engine — finite-volume Euler solver with the HLLC Riemann solver for transonic and supersonic flow up to Mach 5: bow shocks, oblique shocks and expansion fans.
- 2D and 3D — grids up to 4096 cells across in 2D; 3D domains with spheres, boxes, cylinders, wings and Ahmed bodies.
- Your geometry — draw obstacles or import them; walls handled by Brinkman penalisation.
- Engineering output — live drag and lift coefficients, Reynolds number and a probe tool.
- Visualisation — velocity, pressure, vorticity, Schlieren, streamlines and Lagrangian particles.
- Two-fluid flow — independent viscosity and density for stratification and Rayleigh–Taylor studies.
- AI second opinion — local open models can read the screen and help interpret results.
Applications include aerodynamics, ventilation and greenhouse climate, heat exchangers and process equipment. Open it at otomcomposite.eu/CFD or read more on the CFD page.
OTOM SPH
OTOM SPH is a mesh-free smoothed-particle hydrodynamics solver, also running on WebGPU in the browser. Because the fluid is a set of interacting particles rather than a mesh, it handles free surfaces, splashing, filling and mixing naturally, including the molten thermoplastic flow around fibre bundles that matters in composite impregnation and consolidation.
- GPU SPH — density, pressure and viscosity in compute shaders, with prefix-sum spatial sorting for tens of thousands of particles at 60 FPS.
- Turbulence and walls — SPS-LES, vorticity confinement and a log-law wall model.
- Stable at low speed — smooth particle inlets and a bulk-flow stabiliser for very slow flows.
- CAD in the loop — obstacles, containers and mixers from STL or 3MF files, swapped while running.
- Flow insight — streamlines, pathlines, and drag and lift forces on bodies.
- Materials — from water and oil to high-viscosity melts such as PEEK, PEKK, PPS, PP and PA6, and granular flow from hoppers.
