Method of lines

Thank you for the Method of lines article. And I have a note. When moving articles, one should use the "move" tab rather than cut and paste, since with the latter we lose track of an article's history. I now merged back the histories of Method of lines and Numerical method of lines. You can reply here if you have comments. Cheers, Oleg Alexandrov (talk) 00:42, 30 April 2007 (UTC)[reply]

Oleg: Thanks for informing me. I am somewhat new to wikipedia and am not familiar with the finer points of editing, etc. I will use move in future. Regards Griffgruff 18:52, 4 May 2007 (UTC)[reply]

No problem. :) Oleg Alexandrov (talk) 02:02, 5 May 2007 (UTC)[reply]

MUSCL scheme

My compliments for your texts in MUSCL scheme, Flux limiter and more. You added just that little bit of extra understanding to get the bigger picture! On the MUSCL talk page, I added a question, I am not sure whether you are watching that topic, so this is a reminder (no hurry, though) --ArthurVanDam 12:30, 16 May 2007 (UTC)[reply]

Thank you for your feedback and kind comments. Griffgruff 11:27, 17 May 2007 (UTC)[reply]

Note on BC

Hi. Thank you for adding references to the boundary conditions articles. One small note: per conventions references should go after "see also", rather than before (I fixed that). I have a comment. I am not sure how widespread the terminology "first type", "second type", etc., is, I have never heard of it. I am not sure if it is worth mentioning it right at the beginning. I removed it for now, but I can add it back if you think it is widely used. Thanks. You can reply here. Oleg Alexandrov (talk) 06:57, 5 January 2008 (UTC)[reply]

Thank you for pointing out the convention that References come after See also, and for making the changes. With regard to boundary conditions, there is a convention, albeit not universal, that describes them as:

a boundary condition of the first type is called a Dirichlet boundary condition;
a boundary condition of the second type is called a Neumann boundary condition;
a boundary condition of the third type is called a Robin boundary condition.

However, it does seem to be universally accepted that they are presented in the above order when defining them. I have no particular axe to grind on this although my preference would be for them to be described as first, second and third type.

Griffgruff (talk) 20:25, 6 January 2008 (UTC)[reply]

OK, I put back the "types". Cheers, Oleg Alexandrov (talk) 05:12, 9 January 2008 (UTC)[reply]

MUSCL scheme

Hi. Sorry for my bad english. Thanks for your articles MUSCL scheme and Flux limiter. At MUSCL scheme you add some graphics, could you give a link to example of Kurganov and Tadmor central scheme implementation for 1d advection equation? Thanks. Nikolay Khokhlov (talk) 15:50, 23 November 2010 (UTC)[reply]

The Kurgunov and Tadmore scheme is described in their original paper Griffgruff (talk) 14:05, 14 January 2011 (UTC)[reply]

Notification: changes to "Mark my edits as minor by default" preference

Hello there. This is an automated message to tell you about the gradual phasing out of the preference entitled "Mark all edits minor by default", which you currently have (or very recently had) enabled.

On 13 March 2011, this preference was hidden from the user preferences screen as part of efforts to prevent its accidental misuse (consensus discussion). This had the effect of locking users in to their existing preference, which, in your case, was true. To complete the process, your preference will automatically be changed to false in the next few days. This does not require any intervention on your part and you will still be able to manually mark your edits as being 'minor'. The only thing that's changed is that you will no longer have them marked as minor by default.

For established users such as yourself there is a workaround available involving custom JavaScript. If you are familiar with the contents of WP:MINOR, and believe that it is still beneficial to the encyclopedia to have all your edits marked as such by default, then this discussion will give you the details you need to continue with this functionality indefinitely. If you have any problems, feel free to drop me a note.

Thank you for your understanding and happy editing :) Editing on behalf of User:Jarry1250, LivingBot (talk) 18:26, 14 March 2011 (UTC)[reply]

Notification of automated file description generation

Your upload of File:Alston Court and War Memorial, Nayland Village centre.jpg or contribution to its description is noted, and thanks (even if belatedly) for your contribution. In order to help make better use of the media, an attempt has been made by an automated process to identify and add certain information to the media's description page.

This notification is placed on your talk page because a bot has identified you either as the uploader of the file, or as a contributor to its metadata. It would be appreciated if you could carefully review the information the bot added. To opt out of these notifications, please follow the instructions here. Thanks!

Mistake in Kurganov Tadmor scheme?

Hi,

please have a look at the MUSCL scheme discussion. I added a section there about the local propagation speed which I think is different compared to the original algorithm. If you find some time it would be great if you could review that.

Besides that, thanks for the great page.

Many thanks for your feedback. I have made the correction.
