Acceleration calculate in CFX
 
Hello,

I have a simple fluid flow in a spiral tube and I have results: velocity, force, etc. standard results. I need to calculate acceleration vectors. I done it in MathCAD. I exported results (velocity, nodes, coordinates), and I calculated accelerations. Ok. But how can I calculate (and plot) acceleration in CFX? Because must derivation the velocity for accel., and in the CFX CEL function is not able to derivation, only integration...or? I thinkink about this: F=ma...because I know the forces.. Has somebody any idea?
