WebbIn order to save materials and reduce the weight of the structure, the section size of the beam will vary with the length of the beam. Therefore, in the steel frame structure, in addition to the standard form of joint area, there are also different beam heights on both sides of the column in the form of special joint area. WebbAn elliptic system of M(> 2) singularly perturbed linear reaction-diffusion equations, coupled through their zero-order terms, is considered on the unit square. This system does not in general satisfy a maximum principle. It is solved numerically using a standard difference scheme on tensor-product Bakhvalov and Shishkin meshes.
