Hello Everyone,

I am currently trying to do a simulation of a surfboard. I have four forces from the top of the board (pointforces: both feet of the surfer and the shear force, gravityforce: Weight of the board itsself)
and one pressure force from the down side (force from water to board). I want to get the maximum stretch of the board and the position of it.
The material of the board has a Youngs module which is 30000 N/mm^2 and a Poissonnumber 0.1 the Density is 2 g/cm^3.
For me everything I did seems legit but the results are impossible (they are way to high).
Does anyone knows what i am doing wrong.

P.s.: i am very new to simulation programms [upsidedown]

Kind Regards
