Dear REEF3D Team:
I have a question: I have calculated the scour depth of the pier by the water flow, and now I want to output the water flow force data on the surface of the pier, how should I deal with this? I used P 81 to define a force calculation range, but the output data is only "time, Fx, Fy, Fz", and the data format I want is "x, y, z, Fx", where "x, y, z" represent the three-dimensional point on the surface of the pier, and "Fx" represents the water flow force in the direction of the point x(or other direction).
Looking forward to hearing from you.

Hei.
I don't know of any option that would do exactly what you want. However, you could try is defining multiple force boxes with P 81, minimum size will be one cell, and use that to get your area distributed forces.
