The FEniCSx Form Compiler
copied from cf-staging / fenics-ufcxFFCx is a new version of the FEniCS Form Compiler. It is being actively developed and is compatible with DOLFINx.
FFCx is a compiler for finite element variational forms. From a high-level description of the form in the Unified Form Language (UFL), it generates efficient low-level C code that can be used to assemble the corresponding discrete operator (tensor). In particular, a bilinear form may be assembled into a matrix and a linear form may be assembled into a vector. FFCx may be used either from the command line (by invoking the ffcx command) or as a Python module (import ffcx).
