Hi Jean-Michel,

Thanks for the additional information.

The division by zero error you are experiencing is different to the floating point problem reported by AMD Athlon users. There was a bug in the initial release of Version 17.00 which caused a "divide by zero" error when the flare tangent angle at the throat of a "Le Cléac'h" horn was 0 degrees. If you still have the problem with the most recent Hornresp release, Product Number 1700-071110, could you please supply me with a typical set of input parameter values that generates the error, so that I can investigate further - many thanks.

Taking your comments into account, I have relaxed the restriction on T so that the maximum permissible value is now 1,50. The throat acoustical impedance predictions remain valid with this slightly higher setting - I was thinking of much larger T values in my previous message :-).

< < … his preferred T value was 1.3415 > >

T values to four decimal places - wow, that is certainly being precise :-).

Thanks again for the feedback!

Kind regards,

David
