Meshing an irregular part in Abaqus

[kumara123]

Hi,
I want to model a pile penetrate into soil media and have a problem with meshing the model. I always get an error saying the elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively. Previous researchers used a special method by using special shape as shown in attached figure (black and white figure). I am following the same procedure but could not mesh properly as the figure (green). I have tried by introducing more seeds but then it becomes an un-meshable partition. Can anyone recommend me a method to mesh that part.

Thanks.

I believe that what you are trying to achieve can be done by first sectioning the part and than appliying mesh controls in the meshing module of abaqus. I attached some screen shots.

Hi,
Thank you very much for your time. The problem is once I partitioned up to the boundary it cause a problem when running the model. Boundary consists of the infinite elements and error says "Infinite element 274030 instance PART-1-1 is not properly connected a non-infinite element. It must share an entire face with one and only one non-infinite element". I am trying to do meshing without partitioning up to the boundary as attach figure. But I still get the error (Infinite element 400442 instance PART-1-1 is not properly connected a non-infinite element. It must share an entire face with one and only one non-infinite element). figure shows error causing element. Do you have any suggestions?

Thanks.
