Hello all,
wen i try to compile my udf i have this error :
air.c ..\..\src\air.c(31) : error C2198: 'SV_is_point_in_cell'ÿ: pas assez d'arguments pour un appel
..\..\src\air.c(75) : error C2198: 'SV_is_point_in_cell'ÿ: pas assez d'arguments pour un appel

pls help me i need to fix this

If you look this example: https://www.sharcnet.ca/Software/Flu...udf/node72.htm

RP_Cell() might need the #include "surf.h"

thx for ur answer, but i try it nd i still have the same problem

There were also some other differences between your code and the example. Maybe you should copy the example as much as possible.
