Interpolating a profile of a surface

A colleague gathered experimental velocity data in the vertical, diagonal, and horizontal direction of a rectangular duct. The velocity profiles were given to me in these three directions. Attached is a picture of a table that was created in excel with the velocity values (bold) for the three directions. I need to fill in the rest of the table so that I can create a function with x and y inputs for the whole surface that I can use for my input velocity condition in Star. What would be a good way to interpolate this table? It is non-linear, so that's where I'm a little stuck.

can you plot the vertical, horizontal and diagonal data so that we can see the trend?

Unfortunately I do not have permission to post the plots. Maybe I can approach this another way. I have an X,Y,Z table with the values that I do know. Could I just insert that in to Star and then create a Field Function to do the interpolation? If that's a possibility, is there a tutorial that I'm unaware of that gives an example?

You can post the data (in your attached picture) but not the plots of them?
It is easier to decide what type of interpolation is needed when we can see the trend |
