Hello Michael,

Yes, now it works well. Thank you.

I tried to install ngsxfem but it doesn't seem to work. My laptop runs Ubuntu 18.04.3 LTS. The Netgen/NGSolve executables are in /usr/bin/. I go through the following steps (as described on this webpage ).

From my home directory:

Code:

> git clone https://github.com/ngsxfem/ngsxfem.git
> cd ngsxfem
> mkdir build
> cd build
> cmake ../ -DCMAKE_INSTALL_PREFIX=/usr/bin/ -DBUILD_NGSOLVE=OFF -DCMAKE_CXX_COMPILER=ngscxx -DCMAKE_LINKER=ngsld
> make
> make install

Other than some warnings on deprecated declarations, the install goes fine. But when I try to run an examples as follows:

Code:

> cd $HOME/ngsxfem/py_tutorials/
> netgen cutfem.py

I get this error: No module named 'xfem'
So ngsxfem does not seem to be installed. Please let me know where things could be going wrong.

Thank you,
Anand

Hi anand,
where does the installation install to? Is your PYTHONPATH environment variable set to point to that location?
