Developing an Extended IFC Data Schema and Mesh Generation Framework for Finite Element Modeling
Advances in Civil Engineering, 2019 Mesh generation plays an important role in determining the result quality of finite element modeling and structural analysis. Building information modeling provides the geometry and semantic information of a building, which can be utilized to support an ...

Conforming finite element methods for the clamped plate problem [PDF]
, 1975 Finite element methods for solving biharmonic boundary value problems are considered. The particular problem discussed is that of a clamped thin plate. This problem is reformulated in a weak, form in the Sobolev space Techniques for setting up conforming

A conforming discontinuous finite element method for diffusion-reaction equations
四川大学学报. 自然科学版, 2023 For the primal-mixed form of the steady diffusion-reaction equation, a new conforming discontinuous finite element scheme is proposed by using the idea of discontinuous finite element method and the least-square method. Then the method is extended to the
