Such expressions then become valid for any curvilinear coordinate system.

This is a list of some vector calculus formulae for working with common curvilinear coordinate systems.

Curvilinear coordinate systems, such as cylindrical or spherical coordinates, are often used in physical and geometric problems.

Depending on the application, a curvilinear coordinate system may be simpler to use than the Cartesian coordinate system.

With this simple definition of a curvilinear coordinate system, all the results that follow below are simply applications of standard theorems in differential topology.

Coordinates systems for Euclidean space other than the Cartesian coordinate system are called curvilinear coordinate systems.

Equations with boundary conditions that follow coordinate surfaces for a particular curvilinear coordinate system may be easier to solve in that system.

The latter is a curvilinear coordinate system, and (q, q, q) are the curvilinear coordinates of the point P.

While in Cartesian system the equation can be solved easily with less difficulty but in curvilinear coordinate system it is difficult to solve the complex equations.

This more general context makes clear the correspondence between the concepts of centrifugal force in rotating coordinate systems and in stationary curvilinear coordinate systems.

Well-known examples of curvilinear coordinate systems in three-dimensional Euclidean space (R) are Cartesian, cylindrical and spherical polar coordinates.

There are 11 orthogonal curvilinear coordinate systems (to within a conformal symmetry) in which the 3-variable Helmholtz equation can be solved using the separation of variables technique.

The covariant and contravariant basis vectors types have identical direction for orthogonal curvilinear coordinate systems, but as usual have inverted units with respect to each other.

Converting other fields to the curvilinear coordinate system is most easily accomplished with the function SAMPLEXY.

When equations of motion are expressed in terms of any curvilinear coordinate system, extra terms appear that represent how the basis vectors change as the coordinates change.

A system of skew coordinates is a curvilinear coordinate system where the coordinate surfaces are not orthogonal, in contrast to orthogonal coordinates.

Spherical coordinates are one of the most used curvilinear coordinate systems in such fields as Earth sciences, cartography, and physics (in particular quantum mechanics, relativity), and engineering.

The natural choice geometrically is to take , giving the toroidal and poloidal directions shown by the arrows in the figure above, but this makes a left-handed curvilinear coordinate system.

They have developed a scheme based on a finite difference approximation of the equations of motion, applied on a boundary-fitted orthogonal curvilinear coordinate system, inside and outside the drop.

These so-called "forces" are defined by determining the acceleration of a particle within the curvilinear coordinate system, and then separating the simple double-time derivatives of coordinates from the remaining terms.

Michael Eby, a Research Associate working with me, has recently developed a transformation which allows the GFDL MOM2 ocean model to use a curvilinear coordinate system.

If the analysis is done in the curvilinear coordinate system, it is the responsibility of the user to ensure that the proper geometric factor are applied when integrals and derivatives are computed.

The separation of variables for the Klein–Gordon and Dirac equations, in the presence of electromagnetic fields, for a class of curvilinear coordinate systems with a null coordinate is presented.

Analysis techniques for curvilinear coordinate data Analysis of curvilinear coordinate data may be done in the curvilinear coordinate system or in a rectilinear (including lat-long) coordinate system.

If are the contravariant basis vectors in a curvilinear coordinate system, with coordinates of points denoted by (), then the gradient of the tensor field is given by (see for a proof.)
