Terminate »Trial & Error«
Product development by "trial & error" was yesterday. No growing company can afford that these days. Numerica helps you understand the physics behind ideas and products through numerical simulation.
Prototypes are indispensable, but at every stage they only show the status quo: works or doesn't work. Where is there potential for optimisation? Our simulations make it visible and provide the physical basis for sound decisions in the product development process.
»Identifying the problem is more important than identifying the solution, because accurately presenting the problem leads to the solution.«
Albert Einstein
Nothing to »debate«
There is no accounting for taste, but design is definitely not a knock-out criterion. Experience your products in a real environment in front of the physical prototype. Numerica supports your decisions with meaningful key visuals and animations.
»In design, everything has a function. Design has the function of representation. Design has the function of communication. Design has the function of motivation.«

Simulation
Structural dynamics
In dynamics, everything revolves around mass, rigidity, damping & so on. This gives rise to many questions about system behaviour:
With which kinematics do maximum forces & moments occur?
Where should the system be decoupled in terms of vibration technology?
Do machine dynamics influence product quality?
At what frequencies does resonance become an issue?
Numerica provides concrete answers:
- Multi-body dynamics
- Existing natural frequencies
- Harmonious suggestions
- Randomly excited oscillations
- Spectral response
Structural mechanics
Of all the disciplines of simulation, structural mechanics is the oldest. It has grown historically, is the most widely used and answers the following questions about product performance:
Can the component withstand the loads?
Where can we save how much material?
Do we need to stiffen the structure locally?
Is sufficient collateral available?
Are the deformations within limits?
Numerica provides concrete answers:
- Deformations, stresses, strains
- Optimum wall thickness distribution
- System stiffness, contact behaviour
- Stability (buckling / bulging)
- Verification & operational stability
Fluid dynamics
In fluid dynamics (CFD), most applications focus on the physical variables of pressure, velocity and density as a function of temperature and the phenomena of turbulence, phase change and particle transport.
Is the volume flow sufficient?
What is the pressure loss rate?
Where do the particles settle?
Do phase changes occur?
Does the fluid influence the structure?
When is a steady state reached?
Numerica provides concrete answers:
- Flow velocities
- Pressure ratios and pressure losses
- Condensation and evaporation
- Particle transport and sedimentation
- Coupled heat transfer
- Phase distributions
Thermodynamics
Pure temperature field calculations are rare. We usually consider the influence of thermodynamic variables and interactions in a multi-physical context coupled with fluid dynamics, structural mechanics and electromagnetics.
Does thermal stress lead to component failure?
What are the effects of coatings?
Which cooling concept is the most effective?
Does radiation need to be taken into account?
What influence does thermal lift have?
Does the constriction resistance have a significant influence?
Numerica provides concrete answers:
- Temperature distribution in the assembly
- Influence of insulation and environment
- Conduction, convection, radiation component
- Defusing thermal hotspots
- Thermally induced stresses and deformations
- Thermal stress of electronic assemblies
Electromagnetics (LF)
Electromagnetic fields play a major role in electronic components. When designing transformers and coils as well as in connection technology (connectors), we consider electromagnetic fields, currents/current densities and the resulting heating.
Do (vortex) flows cause heating of the structure?
How high do the current densities get?
Do relevant eddy current effects occur?
How many losses are generated in the component?
Which loss mechanism is dominant?
Numerica provides concrete answers:
- Electromagnetic field distribution
- (Eddy) current densities and resulting power losses
- Electrically induced heating of components
- Shares of individual loss mechanisms
- Inductances and magnetic coupling factors
Electromagnetics (HF)
Electromagnetic radiation is everywhere. The interaction between radiation and materials (e.g. metal) presents engineers with new challenges time and again. High-frequency systems such as antennas (Bluetooth, WLAN) must be optimally designed and function perfectly in all installation situations.
What exactly does the radiation pattern look like?
Is the radiation of the HF system homogeneous?
Are there "dead" sectors?
How sensitive is the adaptation network to certain installation situations?
How does the radiation pattern change in certain installation situations?
How far away from metal must the antenna be to exclude negative influence?
Numerica provides concrete answers:
- Radiation characteristics of the HF system or antenna
- Ambient influence on radiation pattern and matching network
- Optimum installation situation for optimum radiation
- Antenna and matching network layout and design
Visualisation
Keyvisuals
Numerica supports your communication process with detailed key visuals. Eliminate design as a knock-out criterion. See your products photo-realistically before the first real prototype and make the right decision right from the start.
Numerica provides concrete answers:
- Static renderings
- Exploded views
- Interactive 3D visuals
- Logo & product animations
- Image videos incl. audio
XReality
The new visual dimension in product development: we support your communication process during the development phase through the targeted use of virtual reality, mixed reality and augmented reality. More and more customers are trusting in this realistic form of presentation.
New perspectives with many advantages:
- Real dimensions become "tangible" and "experienceable" (no limit due to monitor size, etc.)
- Interactive streaming for augmented reality (ISAR) through remote rendering on local servers or via the cloud
- Virtual measuring, sketching and designing directly in space using the Stylus XR Pen
The future? It's already here:
with ARES (Augmented Reality Engineering Space), CAD data and simulation results are visualised and manipulated in an augmented reality environment. Virtual prototyping thus reaches a completely new level of efficiency.
