Need someone that can show the analysis of a net, Suspended at the surface by floats and bouys, anchored to the bottom continously, 1000 yards in diameter,circular in shape. Mesh is 1/2", material is extruded poly.

What kind of 'analysis"?

An analysis of its ability to float?
An analysis of its ability to hold fish?
An analysis of its ability to avoid damage in a moving current?
...

More information is needed.

the FEA needed has been requested by Florida DNR. they wish to see a computer model of the net simulating the effects of waves and current on the system. No software company I have found has a 3D modeling program that will simulate the nylon net strands and show the resistance to current or the elasticity of the net as waves are passing through it. Because of the nets size, when a wave first impacts the net, the time duration of the frequency of waves means that when that wave has completed its run through, there are as many as 20-25 more waves interacting with the net. I need to show in an animated program the proccesion of waves through the nets with stress points and tensions applied. Shearing strength of the nets, the mooring system as a whole. So far the only studies that contian the kind of info that I need have been done on single point mooring systems with a hexagonal ball shaped net, or gravity pens of much smaller diameter, (60 meters), that are not moored to the bottom in a constant manner. Additionally, small flat net panels 10 X10 meters have been used but not with the same mooring systems or showing wave and current deflection.
