WebSet up the SNES VI solver¶. To slve the problem we use the variational inequality solver SNES provided by PETSc.. To use the SNES solver we need to provide suitable function to assemble the residual and the Jacobian, as for the Netwon solver, but with few differences. A class doing this job ggiven the the FEniCS form, the Function and the BCs is provided … WebNext generation FEniCS problem solving environment - dolfinx/petsc.py at main · FEniCS/dolfinx

WebFirst, install FEniCS, version 2024.1. Note, that FEniCS should be compiled with PETSc and petsc4py. Then, install meshio, with a h5py version that matches the HDF5 version used in FEniCS, and matplotlib. The version of meshio should be at least 4, but for compatibility it is recommended to use meshio 4.4. WebNov 19, 2024 · 无奈在新的虚拟机上安FEniCS竟然可以一步到位，却在隔天安了PETSc 3.16 后，又出现了相同问题。原来是高版本的PETSc会和apt-get的FEniCS冲突，apt-get的FEniCS软件包是基于低版本的PETSc构建 （例如ubuntu1804仅提供 PETSc 3.7）。因此选择从源码自行构建FEniCS。
