Thank you a lot Mike !.You explained everything perfectly!May you also know which is the thickness and the density of the discs at Aqwa(without need to draw them at spaceclaim)?
And when i create several adjacent line bodies on each side of the spar for using more beams for one fin,error for mesh appears again:
How is it possible to adjust this kind of problems.Here i reduce element size a lot at mesh...but it takes so long to solve the hydrodynamic diffraction.Is there any other way not to have errors like the above?
Thank you again and again!!!
