You may end up with alot of small sections but its a work around solution to save having to figure out how to program a UDF

You can find it in documentation. For ready reference I am giving a specimen for two data points referred by you. x, y in meters and temp in K. ((airinlet point 2) (x 370 370 ) (y 0 50 ) (temp 873 923 ) )
