Normal Vector on Curved Surfaces
For a radial fan i have to calculate the rate of mechanical work performed at moving walls, which are fixed in the relative system. To calculate this work i need the compute the unit normal vector on the wall area elements. Normally, these elements have curved surfaces (eg. blades). How can i access these normal vectors with a UDF ? Or is it possible do compute them with a simple custom field function ?
