nguyenthong_BK	Dear all, Does we have an example (in examples of Telemac 2D) where we use spherical coordinates for the domain? Thank you very much for any your information. Best regards Thong NGUYEN HCMUT, VN

Hello Thong,

There are several possibilities, which become misleading. You have the keyword "spherical coordinates" (yes or no), and you have the keyword "SPATIAL PROJECTION TYPE" : 1 for cartesian, 2 for Mercator, 3 for spherical.

SPHERICAL COORDINATES = YES will require SPATIAL PROJECTION TYPE = 2 or 3.

An example with :

SPHERICAL COORDINATES = YES SPATIAL PROJECTION TYPE = 2

is : ondem2 or m2wave

Be sure to use version 7.1, where the treatment is much more accurate, however it will work in 3D only in revision R1.

With best regards,

Jean-Michel Hervouet
