Problems while sweep partitioning of cells in Abaqus 6.14

[varun636nimbus]

Hello,

I am trying to generate a structured hexahedral mesh on a Swept Fibre Geometry along a wire spline(in total 5).I partition the circular cross section faces of each spline and then i partition the volume cells by sweep partitioning approach .

In 4 out of 5 cases i am able to successfully sweep the partition, but in the fifth spline it does not allow me sweep the partition and asks me to choose another strategy .I am attaching with this query the photographs of my model's photographs.

I create the face partition in the top view and sweep it towards the bottom face for partitioning the cell.The green splines are the ones with successful partiton. Leftmost fibre has the sweeping problems.Top View image has the face partioned i.e is to be swept and Bottom view shows the partition that is successfully executed.

Is there anyway to carry out the sweep partition .
I tried to explain the problem as concisely as possible please let me know if there i can supply any additional information in case of lack of completeness of the descriptiom

Thanks in Advance

It looks as though the parts are symmetric about a plane through the centre. If you're having problems then why not just copy and mirror one of the parts to create the full assembly. Sometimes problems can occur in partitioning parts as an edge or point might just be off so you have to look for an easier route.
