WebI am master student and doing an assignment of Finite element method. In the instruction I could not understand the derivation of the weak form, which should not be difficult. I'm sorry for posting this easy and most likely not helpful question for other people. So the derivation is about the weak form of the integral formulation of 4th ODE. WebOct 5, 2024 · The strong and weak statements of the problem are equivalent. Since finite elements uses the weak form of the problem statement, we can either derive the weak form from the strong form or using the principle of virtual work. The preferred approach is chosen on the basis of convenience. We can derive the weak form from the strong form as follows.

Weak form and strong form - Wikipedia

WebThe weak form of the PDE means that you have, in some sense, "fewer constraints on the kinds of functions that you can use" to construct a solution. To put it into perspective, recall that in FEM, you look for a solution of the form: ∑ j u j ∗ ϕ j ( x) WebApr 19, 2024 · First the important part of finding weak solutions to PDEs is rewriting a PDE into the weak form aka L ( x) = 0 ⇒ ∫ L ( x) v d x = 0 where L is some differential operator (using the integration by parts bit makes finding numerical solutions easier but it is not strictly nessary).
