In testing the complex number option on FEniCSx, I got an assertion error. %python3 CmplxPoisson.py float64 complex128 <class ‘numpy.float64’>****THIS IS SUPPOSED TO BE <class ‘numpy.complex128’> Traceback (most recent call last): File “/Users/carlajadamson/Documents/CmplxPoisson.py”, line 16,…

zsh (not mac-specific, but it is the default shell on macs) expands globs a little differently from bash, you need to put strings with * that aren’t file globs in quotes to prevent glob expansion: conda create -n env3-10-complex -c conda-forge python=3.10 fenics-dolfinx 'petsc=*=complex*' mpich ba…

The output was no matches found: petsc==complex This is what was downloaded from FEniCSx petsc conda-forge/osx-arm64::petsc-3.20.5-real_h7646cce_100 petsc4py conda-forge/osx-arm64::petsc4py-3.20.5-real_hd567e68_100

Please provide the full command that you were running, and the full output (not just the last line of the error message).

[image] rsn766: conda create -n env3-10-complex -c conda-forge python=3.10 fenics-dolfinx petsc==complex mpich I cannot reproduce this on my linux system. @minrk do you know why this isn’t working on osx-arm64?

used yours and got the complex download: petsc conda-forge/osx-arm64::petsc-3.20.5-complex_h8e9ca2b_0 petsc4py conda-forge/osx-arm64::petsc4py-3.20.5-complex_h1f0f144_0 However, when I run the program: python3 CmplxPoisson.py float64 complex128 <class ‘numpy.float64’> …

Please provide the output of conda env export
