The cylindrical coordinate system is a 3D coordinate system similar to 3D Cartesian coordinate system. The point is defined by three coordinates (r,θ,c) as shown in Fig. 5 where r is the radial distance from the origin, θ is the angle between the radial line and the x-axis, c is ...
4) cylindrical coordinates 圆柱坐标系 1. Based on FDTD difference expressions and eigenfunctions of Maxwell functions in cylindrical coordinates, mesh wave impedances (MWIs) in 2D and 3D cylindrical coordinates were introduced. 从圆柱坐标系下麦克斯韦方程的时域有限差分式和特征解出发 ,引入了二维和...
Here, the method is extended to multi-group neutron diffusion in 3D cylindrical coordinates. Unlike the Cartesian geometries, each direction needs separate treatment in case of the cylindrical geometries. Therefore, the extension is neither trivial nor straightforward. The developed method is tested by...
2) cylindrical coordinates 圆柱坐标 1. This paper presents the formula of subaperture overlapping by introducingcylindrical coordinates( θxr ). 本文推导了圆柱坐标下的孔径拼接公式,并利用新的拼接公式模拟测量了一圆柱体面形。 更多例句>> 3) cylindrical-coordinate system ...
Then I converted stress tensor components to Cylindrical Coordinates using cylindricalCoordinates.H: Code: const volVectorField C = mesh.C(); // Initial Coordinates const volVectorField CT = C-origin_; // Transfomed Coordinates forAll(C,i) { scalar teta = std::atan2(CT[i].y(), CT...

2.The Fourier transformations about the azimuthal angle and Hankel transformation about the radial direction have been used to convert the basic equations of elasticity into a non-homogenous first-order ordinary differential equation system incylindrical coordinates.在柱坐标系下,利用关于方位角的Fourier变换...
Once open comsol model builder window after selecting the 3-D option, by default it is showing (x ,y, z) coordinate, that's fine when I am solving energy equation for rectangular block. But, (x, y, z) coordinate system can not be used for solving cylindrical system. ...
[[59], [60], [61], [62]] developed an analytical solution for the heat conduction equation in spherical and cylindrical coordinates system of FGM structures with both radial and tangentially varying material properties where the power law is used to analyze the variance of traits. Distributions...
