Computational Fluid Dynamics, CFD for short, can be used to make precise calculations for the flow behaviour of your components without the…

Adiabatic (adiabat, from ancient Greek ἀδιάβατος (adiabatos) "not passing through") is a term used in flow simulation. No heat exchange takes…

Boundary conditions are the forces or specified deformations that act externally on a closed system.  In general, they are all values that…

Buckling refers to the yielding of components under compressive load. It thus describes the loss of stability of a mechanical component that…

CAE stands for Computer-Aided Engineering. This term covers all computer-aided solutions for work processes in development and design.

In the field of technical calculation, we speak of contact when two different components are in contact and can be moved in one or more…

Convection (Latin convehere = to bring together), or heat flow, refers to the energetic transfer of heat from one place to another

In materials, the term "creep" refers to the time- and temperature-dependent deformation of a material under constant load. These…

The finite element method (FEM for short) is a numerical calculation method. The problem or calculation area is divided into a finite number…

Computational fluid dynamics (CFD) is an established method in fluid mechanics. Its aim is to solve fluid mechanics problems approximatively…

Laminar flow (lat. lamina "plate") is a movement of liquids and gases in which no visible turbulence (turbulence/crossflow) occurs (yet):

The modulus of elasticity is a material parameter from materials engineering. It is often also referred to as tensile modulus, elongation…

One speaks of plasticity when a component is subjected to a load beyond its elastic limit. Whereby the materials retain the resulting shape…

Strain hardening is the behavior of materials subjected to plastic stress. The mechanical strength changes with the plastic deformation.…

A steady-state simulation is a calculation in which no change in the event over time is taken into account. This term is common for…

Elongation is the deformation of a component in relation to the undeformed geometry. The strain is therefore dependent on the acting force…

Structural mechanics is the calculation of deformations, forces and internal stresses in solids, either for the design of new or the…

Tensile strength, also known as tensile strength at break, is a material parameter that indicates how strongly a material can be loaded. It…

Thermal radiation is the transmission of heat by electromagnetic waves emitted by a physical body. A typical heat radiation via…

A transient simulation is a calculation in which time-dependent influences are taken into account. In structural mechanics, this is also…

One speaks of turbulent flow when turbulence of any magnitude occurs in the motion of the liquid or gas. Turbulent flow is much more…

The volume-of-fluid method, or VOF method for short, is one of the standard methods when it comes to calculating two-phase flows.

In engineering, stress describes the strain on components and materials. Stress is the force acting on a given surface.

Testing and calculation are complementary fields for the verification and optimization of designs. Calculation helps to achieve better…
