AQWA Problem

Hey everybody
I'm beginner with AQWA, but I need it for my master thesis. My thesis is bout an moored FPSO. when i run AQWA with a Geometry, this error comes:

ELEMENTS MUST BE AT LEAST 1.000 * FACET RADIUS APART - ELEMENT 3887 VIOLATES THIS CONDITION

I am not 100% sure why you get this error but you can just re-mesh it may solve it, unless you have very thin body in the water ...

well, I did. but it doesn't changed. this error comes up again. and by "very thin body in the water" you mean low draft, no it's not, at least 12 meter draft (even in comparison with other dimensions it's not low).

thanks by the way

By very thin body in the water I mean that you have two (or more) surfaces/plates which are very close to each other (or maybe it's only 1 surface). In AQWA your surfaces must "add-up" to a displacement body, in other words they need to enclose some volume.

You mean I need a enclosed surface?
A Body with empty inside?
