I have been using Netgen/NGSolve on 64-bit Ubuntu 16.04 LTS for the past 6 months. I installed it using Conda.
Only recently have I encountered the following error
NameError: name ‘dx’ is not defined
with codes involving dx.
I followed the advice on:
Can not run navierstokes.py example
(Can not run navierstokes.py example - Kunena)
but in vain.
netgen 6.2.2006 py37he358ceb_3 conda-forge
ngsolve 6.2.2006.post48 py37_0 ngsolve
Can you please help me fix this?
