"Paris, 2018. SimTech's engineering team had been working on the simulation of a new electric motor for three days. The CAD model, with its 14,782 geometric features, had turned their supercomputer into a digital snail. 'A simulation that should take 4 hours is taking 86,' sighed Thomas, a senior engineer. 'And we still have 7 configurations to test before Monday...'"
Does this situation sound familiar? In a world where time-to-market becomes more critical every day, the endless preparation times for 3D models for numerical simulation constitute a major barrier to innovation. A recent study reveals that more than 70% of simulation failures are attributable not to solvers, but to geometric defects present in the CAD models used as the basis for calculation.
The path from a CAD model designed for manufacturing to a model usable for simulation is fraught with obstacles: unwanted gaps, overlaps, self-intersections, or simply excessive complexity that transforms each calculation iteration into a computational marathon. These problems may seem technical, but their consequences are very real:
Facing these challenges, we offer tools specifically designed to streamline the transition from CAD to simulation. CADfix offers a complete range of functionality to import, repair, and transform CAD geometry automatically or interactively before analysis. Meanwhile, CADIQ ensures the geometric qualification essential for guaranteeing reliable results.

"Monday, 8:30 a.m. The SimTech aeronautics team spent the weekend running a critical airflow simulation. Result: complete failure. 'Again!' exclaims Sophie, the senior engineer. Examining the CAD model, she discovers a tiny free edge, invisible to the naked eye, but fatal to the mesh. Three days of computation lost because of a geometric defect of a few microns."
This story is repeated daily in the industry. A recent study reveals that 70% of simulation failures are not due to solvers, but to geometric defects hidden in CAD models. These invisible imperfections—free edges, degenerate faces, non-tangent surfaces—silently sabotage your most sophisticated numerical analyses.
CAD qualification for simulation is not just a technical step; it ensures that your critical decisions are based on solid foundations rather than numerical illusions.
What if your next simulation succeeds the first time?
The world of simulation and CAD (Computer-Aided Design) is vast and intricate. Interoperability between CAD models and simulation tools is vital to ensure accurate and reliable results. Discover here how tartan meshing fits into this context and how the solution CADfix stands out in this industry.
Throughout a product's lifecycle, designs are revisited by various experts, crossing multiple departments or even partnering companies. Swiftly detecting changes and discrepancies between different CAD models and mesh data from simulations is vital. CADfix provides three innovative tools for CAD, CAE, simulation, and advanced manufacturing. These tools guide users in effortlessly identifying variances between CAD models and meshes.
The Medial Object technology represents a major advancement in the preparation of CAD models for numerical simulation. Originally developed at Queen's University in Belfast in the 1980s, this revolutionary approach transforms complex 3D models into lighter skeletal representations better suited for numerical calculations. Engineers facing growing challenges in CAD interoperability and complex modern geometries find in this technology a solution to significantly reduce preparation time while improving analysis accuracy.
With the constant increase in the complexity of 3D designs, traditional methods of preparing models for simulation are reaching their limits, resulting in extended delays and sometimes inaccurate results. Medial Object Technology, integrated into advanced software solutions, offers a high-performance alternative that revolutionizes numerical simulation workflows and opens new perspectives for product optimization.
In the realm of engineering simulations, the preparation of CAD models is a critical step that determines the accuracy and efficiency of the simulation process. CADfix, a powerful tool in this domain, comes to the forefront with its innovative Geometric Reasoning technology, transforming mid surfaces of solids into skeletal representations packed with comprehensive information.
In the world of modern engineering, numerical simulation constitutes an essential pillar of product development. However, a major obstacle persists: the preparation of CAD models. A recent study reveals that engineers spend up to 70% of their time preparing geometries before even launching their analyses. Volume extraction represents one of the most critical and technical steps of this process, capable of radically transforming the accuracy of results and the efficiency of simulation workflows.

This story is repeated daily in industry. CAD models designed for manufacturing are often precision monsters that are useless for simulation. Imagine an architect who, to calculate the living area of a house, would start by modeling every brick, screw, and electrical outlet.
Intelligent simplification of CAD models can reduce calculation times by up to 70% while preserving the accuracy of the results. Like removing screws from an assembly when you just want to analyze its overall aerodynamics.
