To get the maximum and minimum v component of velocity I'm using: maxVal(velocity v)@Domain minVal(velocity v)@Domain This gives me the maximum and minimum values of the v component of velocity. But I also need the location of those values. Is there a way to do this? Thank you.

I've found that the minimum velocity is nearest to node 9234. Is there a way to determine the coordinates of that node with respect to my geometry? Thanks

 August 31, 2012, 05:52 #5 Member   DB Join Date: Apr 2011 Posts: 81 Rep Power: 8 Hi, Define a point with variable Maximum/Minimum of the variable you are looking for. Then export co-ordinates of these points, by export option in file, or probe X, Y and Z co-ordinate of this point if fuction calculator JuPa likes this. __________________ -D.B Last edited by D.B; August 31, 2012 at 06:13.
