Hi there.

The error message here says that the computer can not connect to GitHub.com.

It looks like the terminal doesn’t have internet access on that port.

This doesn’t look like an error from the python package itself.

By the way the CPP weight windows are being developed and these are faster. You might also want to look at installing this branch of openmc Global Weight Window Generation via CAPI by pshriwise · Pull Request #2359 · openmc-dev/openmc · GitHub

Thank you very much. I’ve already installed the weight window generator

I have another question. Can weight windows method be used in eigenvalue calculation?

[paulromano]

They can be used in eigenvalue calculations but generally will not give you the same kind of improvement in figure-of-merit as what you would see in a fixed source problem.

May I ask whether CPP weight windows can be used now? How can I install and use it?

[Shimwell]

Currently you would have to clone repository fork, checkout the branch and install from source.

Whether Weight Windows must use a 3D mesh or 3D tally?Can I use a 2D mesh in a 3D model?

[Shimwell]

I’ve not tried a 2D mesh with weight windows. If you give it a go let us know how it goes and if you get any errors

I use 1D, 2D and 3D global flux meshes for the weight window. The results show that their global heating is almost the same, but the way particles penetrate is very different. I don’t know why the result is like this, so does it mean I can use different mesh forms for specific problems?
