I am still mystified because of this one. The reason being that for some elements, the radius/thickness ratio gives me a warning and for a bunch of elements, it returns me an error (notifying me of the reason that it violates the assumption of a shell element). I mean, what is the assumption of a shell element? As has already pointed out in one of his previous comments that the shell elements were originally designed to have thickness less than the element length, but where is this 'radius' coming from within the warnings and errors. I mean how can an element have a radius, either it can straight (if linear) or there can be a sharp angle within the element itself (if quadratic). What does this element radius actually mean?nWhy does some elements only return a warning because of radius/thickness ratio and why does some return an error? What is the standard used by ANSYS to decide that this element will only result in a warning and this element will result in an error (which would make my analysis to come to a halt). Can it be because of geometry?nHow can I solve this problem?n,unfortunately I cannot share any snaps of the model currently. The boundary conditions are fixed supports. But this error is occurring far from the fixed supports, without any force applied, without any contact, and I believe it is solely because of the element size and thickness given to that shell element, since solution doesn't even start to solve and straight away stops, giving this error.n
