Nonlinear spherical area load applied to an ellipse surface in PLAXIS 3D

Dear Rushan,

My approach on this would be to create multiple circular surfaces (intersect them) to create zones at which the load can be considered constant. Each zone can be defined by the increment from the edges to the centre of the circle. Obviously, the more you have, the better distribution, but also smaller elements (e.g. if each surface is of a few cm). 

Another option is to model the loading by various dummy soil volumes that their only purpose would be to provide a unit weight simulating the distributed load applied.

By the way, that is a nice feature we should implement in the future.

Dear Stefanos,

Thank you very much for a quick reply.

I had not thought of the ring stripe idea, it is an interesting idea. The only thing I came up with was to divide the circle into several sectors (like pieces of pizza) and set the vector or free increments in them. But the result is so-so:

I can not say that such an option would be much in demand, but it is better when it is =)

Great thanks!

Hello Rushan, 

The pizza approach (you can call it like that, I guess) is also a nice idea. Indeed, none of the results is exactly what we want but at least it is something to work with.
