Simulate Early, Simulate Often... In Rhino
I try to calcultae the strength of keel beam
But first I have to find the loads and that depends of loads of hogging and sagging.
Also it is confsing where the strains come. Is there somebody how can give me a push in the good direction.

First, let me say I am not a marine engineer or designer. However maybe this is helpful:
First I split the wetted faces of the hull amidship so I could specify separate loads to the front and rear sections.
I then applied 2 separate hydrostatic loads (one forward and one rearward) to the corresponding wetted faces of the hull. When specifying the water surface for each hydrostatic load, I oriented the surface normal so the water surface was aligned with the planar water surfaces depicted here for the "hogging" configuration.
For the "sagging" configuration, I made a copy of the model and redefined the water surface to align with the planar water surfaces depicted here.
Does this make sense? Is it helpful?
I will try and I let you know
