WebForm language ¶. Form language. UFL consists of a set of operators and atomic expressions that can be used to express variational forms and functionals. Below we will define all these operators and atomic expressions in detail. UFL is built on top of the Python language, and any Python code is valid in the definition of a form. WebFEniCS is a popular open-source computing platform for solving partial differential equations (PDEs). FEniCS enables users to quickly translate scientific models into efficient finite …
