Dear all
I'm a beginner in using flow-3d. I tried to simulate wave and added wave absorber as component. However the simulation didn't run well, it displayed like this "Abnormal exit from simulation". I opened warning box and something like this appeared

****************************************
** fatal error **
** downstream direction vector is **
** not defined for component 1 **
****************************************

What should I do to solve this?

When you use the wave absorbing component type, in the wave absorbing settings in the component properties window, you need to define XYZ points for the starting point and downstream direction.

Thank you very much for the answer. Now the simulation works really well.
