'moving geometry' is a correct and usable phrase in written English.
You can use it in any context where you need to refer to geometric shapes that are in motion or changing shape/size. For example: "The shadows cast by the moving geometry of the buildings created a fascinating pattern of light and dark on the pavement."
Complex, possibly moving, geometry is treated through the use of structured overlapping grids.
The versatility of the method is demonstrated via several numerical examples, in both static and moving geometry, ranging from low Mach number nearly incompressible flows to supersonic flows.
The no-penentration condition for the moving geometry is satisfied by superposing a homogenous solution to the Poisson's equation for the streamfunction.
A fully second-order accurate implementation of the AMP scheme is developed in two dimensions based on a fractional-step method for the incompressible Navier Stokes equations using finite difference methods and overlapping grids to handle the moving geometry.
In the event that the target is moving, geometry and motion characteristics are usually utilized to reduce the NLOS effect such as through Kalman filtering [12 14].
We develop a high order numerical boundary condition for compressible inviscid flows involving complex moving geometries.
However, its extension to time-dependent problems with body-fitted moving geometries is far from straightforward.
We will review the state of the art in integral equation methods for the solution of the heat equation and fluid flow in moving geometries.
To achieve large 3D computations the method must be coupled to efficient algorithms for velocity computations, including a good treatment of non-homogeneities and complex moving geometries.
The two methods have been widely employed to solve partial differential equations in complex and moving geometries for applications ranging from solid and fluid mechanics to biology and geophysics.
The conservative immersed interface method for representing complex immersed solid boundaries or phase interfaces on Cartesian grids is improved and extended to allow for the simulation of weakly compressible fluid flows through moving geometries.
