http://www.cn.comsol.com/blogs/implementing-the-weak-form-with-a-comsol-app/ Recall our simple example of 1D heat transfer at steady state with no heat source, where the temperature is a function of the position in the domain defined by the interval . We imposed the Neumann boundary condition such that the outgoing flux should be 2 at the left boundary () and the Dirichlet boundary … Zobacz więcej The steps for implementing the weak form equation in COMSOL Multiphysics have been discussed in this earlier blog entry, thus we will not repeat them here. To view the stiffness matrix and load vector, right-click Solution 1 … Zobacz więcej We mentioned before that it is sometimes desirable not to solve for the Lagrange multiplier — for example, to save computation … Zobacz więcej COMSOL Multiphysics allows us to evaluate and view any of the matrices and vectors mentioned above. All we have to do is to follow … Zobacz więcej When we implement the Dirichlet boundary condition using the Weak Contribution feature with a Lagrange multiplier (as shown in this previous blog post), we … Zobacz więcej Witryna16 paź 2024 · The weak form for any COMSOL Multiphysics physics interface can be viewed by enabling the Equation View. If we compare ( Eq. 10 ) with ( Eq. 9 ) and ( … difference between place and space
