aerofoil geomety in ICEMCFD using script files
 

wellcome; To explain, I have to create script files (file.txt), which can be read in ICEMCFD, in order to generate geometry, domain of computing and create mesh. I have done the aerofoil family. But to define: paroi 1 , paroi 2, inflow and outflow families I have difficulties to get the vertices(4) (x, y)coordinates of the rectangular( or square) domain of computing.I have idea to compute them with consideration of:c=100mm,longer of(square)domain=10c.In this case i need to know how to compute (x,y)of the center of gravitation of the aerofoil.thanks in advance.
