Running NGSolve on Windows (python 3.9) was created by bhaveshshrimali
Hi everyone,
Is it possible to run NGSolve (NGS-Py) on Windows natively? I just switched from python 3.7 to python 3.9. Everything was working perfectly fine up until now.

Yes, but you have to compile NGSolve yourself.

Thanks Christopher, I will give it a go. My immediate resort was Docker and that works seamlessly, but I will try to install from sources over the weekend.

Thanks,
Bhavesh

Hi Christopher,
I tried building NGSolve from source. However it fails. I am not an expert on CMake. Could you help me debug it?

This is the output of cmake --build
Code:
> cmake --build . --config Release --target install Microsoft (R) Build Engine version 15.9.21+g9802d43bc3 for .NET Framework Copyright (C) Microsoft Corporation. All rights reserved.

I have both Microsoft Visual Studio 2017 and 2019 installed on my machine.

Thanks

I was able to build Netgen it seems. However not NGSolve
