General

hello everyone, I’m encountering an issue with installing FEniCSx 0.8 on my system and would appreciate any assistance. I’m trying to install FEniCS using step given at the site:https://fenicsproject.org/download/, but I’m running into the following issue:

1. conda install -c conda-forge fenics-dolfinx mpich pyvista
Channels:

  • conda-forge
  • defaults
    Platform: win-64
    Collecting package metadata (repodata.json): done
    Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  • mpich
  • fenics-dolfinx

Current channels:

So as far as I can tell from the output above, you are on a windows system?
Is that correct?
If so, you either need to:

  1. Use WSL and conda within WSL
  2. Use the experimental dolfinx windows package (without petsc): GitHub - FEniCS/dolfinx: Next generation FEniCS problem solving environment

Windows conda packages are currently in beta testing and can be installed > using:

conda create -n fenicsx-env
conda activate fenicsx-env
conda install -c minrk/label/fenics-windows -c conda-forge fenics-> dolfinx=0.9.0.dev

there is issue with compatibility when I run the demo of solved example of Fenics project , So how I resolve that

What example? Please post a link to the code you are running.

As stated in other similar posts, you are looking at code for legacy fenics, not DOLFINx.
