[CIG-SEISMO] Happy 20th anniversary SPECFEM / bon anniversaire SPECFEM !

[YVON MADAY]

Thanks Dimitri for acknowledging and having kept these notes that I had a very big pleasure to read over... there was indeed most of the things to implement SEM there (actually most of the more easy matters) but there is generally a big gap between i) what is said ii) what is written by the listener and iii) what is done after with these notes. Reading these note, acknowledges that point ii) and after iii) have been done by a team of impressing fellows. In addition, the less simple things I did not speak about have been invented by you during the implementations and make this SPECFEM a success

I am thus very grateful to all of you for this realization, these have certainly the most fruitful hours I spent

Best

Yvon

> The whole story started on April 4, 1995 when Yvon Maday (cc'ed) was kind enough to visit and give us explanations about how to use the spectral-element method, which he had co-developed with Anthony Patera at MIT. Let me thank Yvon again for that, and let me also thank my PhD advisor Jean-Pierre Vilotte for organizing that meeting. Attached are the notes from that meeting, as a souvenir I scanned them and put them in the "doc" directory of the code.
