Hi List,
Hope you can help me with the following issue: I have a motor geometry 'Motor0.geo' that is apparently meshed with Gmsh without any issues, however when I open ‘Motor0.pro’, it triggers an error during GetDP check. The error is shown below,

The line 30 in file ‘Motor0.geo’ is the following (by the way, all parameters have been previously initialized):

M_aai = ( 2/beta )*Asin( M_w / ( 2*oRr ) ) ;


From

http://getdp.info/doc/texinfo/getdp.html

one sees that the correct syntax for functions is with square brackets

Asin
[expression]
Arc sine (inverse sine) of expression in [-Pi/2,Pi/2], expression in [-1,1] (real valued only).

So,

M_aai = ( 2/beta )*Asin[ M_w / ( 2*oRr ) ] ;

Regards,
Fr.





I wonder why no error is shown when open 'Motor0.geo’ instead of ‘Motor0.pro’. Hope you can give a clue, also I can send more information on what the files have in them if required.
Thanks,
Alejandro
