Hello,

 

I have a question, when I want to create a sweep type mesh in a body in the shape of a half cylinder like the one shown in the image but which is formed, in turn, by different bodies to better simulate the growth behavior of a crack. . How can I ensure that on the outermost face there is a certain continuity between the triangular elements of the different bodies that form the solid as a whole. Also, the body that appears without meshing is giving me problems, but I don't know why. Does anyone have any idea why? I am attaching an image showing the details of the method.

 

I hope I have explained myself well, I am attaching a couple of images to clarify my question.

Assuming that you have shared topology in your model (meaning adjacent bodies share overlapping faces and edges) then, start with smallest bodies at bottom, Mesh them with adequate size, then go for wedge shaped one and then the annular cylindrical one. Try to minimize constraint to bare minimum to avoid overconstraining. You can also try multizone method instead of sweep.

I don't know very well how the geometry is shared. Sorry, but I am a fairly new Ansys user. Could you give me more details on how to do what he told me in his previous answer? Thank you.
