[FLASH-USERS] installation of Flash4.3!

[John ZuHone]

Hi Scott and all,

I agree with all of Nathan's points, but I will chime in here with a couple of others.

If you have a FLASH-specific question, it's likely I will try to jump on it, but Nathan is right, just about any of the active developers could handle most issues.

The main reason for that is that the FLASH frontend is very mature, and it is much more likely that if you encounter a bug it is not in the FLASH-specific code but instead is somewhere else in yt. We strive to keep things pretty modular and all of the machinery that handles AMR codes is common to the different frontends that are appropriate (e.g. FLASH, Enzo, Athena, etc.).

But if you have specific issues I would not hesitate to use one of the channels that Nathan suggested for reporting them.

Best,

John

I've had a good experience with it as well, although I have run into a few bugs along the way with re-sampling 3D adaptive mesh data (which may be yt, or may be the yt FLASH module). In the yt 3.3.1 user guide "Loading data: FLASH data" section (http://yt-project.org/doc/examining/loading_data.html#flash-data), it says:

Ancillary test datasets used in the script are also very useful for reproducing bugs, but we are mindful that often people are working with very large and/or proprietary datasets.

If you spot anything that yt is doing incorrectly or see an error or inconsistency in our documentation, please let us know so we can fix it or, if you have the time or inclination, please also feel free to fix issues you come across in yt and submit a pull request. Community contributions in the form of isssue reports and pull requests are extremely helpful. Documentation improvements from newcomers are extremely valuable as well, since it's all too easy to write documentation that assumes too much background.
