Thank you Riku!

Apologies for bumping an old thread, but could the link be re-activated?

Thank you,

I am happy to announce that serpentTools 0.9.3 has been released, and is available for upgrade via pip. The changelog can be viewed via the hosted documentation or through the GitHub release. This is a backwards compatible release, with two main trends. First, many readers now support dictionary-lik...

Wonderful user community, The serpenttools python package will be undergoing a fairly substantial overhaul in the coming months leading up to version 0.10.0 (currently at 0.9.2). The primary goal of this release is to make serpentTools more like a library with generic file objects and containers det...

As an update, I ran select cases with 5 unique random seeds and everything looks agreeable now. The relative error to the reference case with 3-sigma confidence intervals is provided below. The reference is just a single pin directive placed inside a 3D box. fluxerror-tmc.png Thank you all for your ...

All, Thank you for your insights. I hadn't considered the surface crossing and their impact on the random number sequences. That would certainly explain some other similar issues I'm seeing. This is something that should come out when I process the repeated runs. Once those are processed, I'll make ...

Thank you for your reply. I'm using reflective boundary conditions in XY, vacuum axially. I haven't looked at repeated runs yet, but I'll post some results once I get them. As for source convergence, do you have any recommendations on particle settings? I'm using 100K particles per cycle, 200 active...

I believe I have stumbled on a strange geometry related issue. It appears, at least for a simple pin cell, the choice in vertical lattice structure changes the axial flux solution. The model is a single pincell, 360 cm tall with a single UO2 material defined. I have five cases that alter how the 3D ...

Thank you for providing the test file. If you look at the salt's burnup with grep MAT_salt_BURNUP test_dep.m you see an array of zeros present in the file. This is most curious. My best guess as to why the salt has zero burnup would be that it's specific power (MW/kgHM) is zero. The fact that the sa...

Ondrej, Thank you for those nice words! I'm glad you find this a useful tool. Per your first question, setting the axes limits is done through matplotlib, as you expressed. I think the second way, ax = r.plot('burnup', ['absKeff', 'colKeff']) ax.set_ylim(...) ax.set_xlim(...) would be the best. It a...
