Quelltermen
Quelltermen, also known as "source terms" or "source functions," are mathematical expressions used in physics and engineering to describe the distribution of sources or sinks within a continuous medium. They are fundamental in fields such as fluid dynamics, electromagnetism, and heat transfer, where they help model phenomena like mass, charge, or energy distribution.
In the context of partial differential equations (PDEs), a source term represents an external influence that
The concept is particularly important in the Navier-Stokes equations, where source terms can represent body forces
Quelltermen are often introduced as additional terms in governing equations to account for localized effects that
In computational simulations, source terms are discretized alongside other variables to ensure numerical stability and accuracy.
