![]() The segregated step method generates the set of algebraic equations for every physical model under consideration and calculates the resulting solutions for each of those models byįollowing a sequence specified by the user. ![]() ![]() ![]() This step is followed by solving the set of algebraic equations, which provides the physics-related nodal solutions of the model.ĬOMSOL Multiphysics ® mainly employs two methods to obtain the model solution, namely segregated step method and fully coupled method. Typically, the latter is hidden among the core of the commercial software.Īfter that, the application of appropriate loadings, boundary and initial conditions to the domain under study, as well as its discretization into finite elements, determines the matrixĮquation governing the model, in a similar form of the one presented in equation ( 4.27). Then, the physical environments of the problem under investigation are generated by assigning the underlying physics (or multiphysics), mathematical equations, and finite element formulation to the The first sub-step involves the creation of the interconnect geometry (1D, 2D, or 3D), to represent the domain under study, and assign the material properties to the domain. Since it contains all the information regarding the FEM application for interconnect study, it is convenient to divide it into smaller sub-steps. The pre-processing step enables the user to build the model. The method can be split into three basic steps, namely pre-processing, solver, and post-processing .
