Dear all,

I am quite new to this, but I did a lot of research and as far as I know there are no real examples to find overhere.

Anyway, my goal is to write an UDF that will calculate a 3d velocity profile derived from MRI. Per hart beat I have 30 velocity profiles available in a 17x14 matrix. looking quite similar to this: http://www.ila.de/typo3temp/pics/tur...a95adbbee7.png

I am wondering how I should approach to calculate the velocity profile within fluent. Currently I am thinking of using bilinear interpolation to interpolete between the datapoints.

I don't know how fluent loops over the inlet boundary. e.g. I have no clue how to match a face at the inlet to the (interpolated) value within the matrix.

Can anyone steer me into the correct direction?

my raw data are 30 matrices that look like the one below
