Generalized curvilinear coordinate system
WebMay 1, 2003 · A GOCC system allows a coordinate transformation that displaces the “north pole” of the model grid, or the northern grid pole, into landmasses. The north pole of a model grid is where curvilinear … WebMar 24, 2024 · Curvilinear Coordinates A coordinate system composed of intersecting surfaces. If the intersections are all at right angles , then the curvilinear coordinates are said to form an orthogonal coordinate system. If not, they form a skew coordinate system . A general metric has a line element (1) where Einstein summation is being used.
