ABAQUS

surface normal

Dear all,

I'm using abaqus to build a spherical model, which applies C3D8 linear brick element.  I output the connectivities of one element on the surface and the corresponding coordinates. 

For a linear brick element, the four nodes A,B,C and D on the same surface should lie on the same plane.  However, I got two different normals which are from A,B,C as well as A,B,D.

Is it reasonable or do I misunderstand something?

I started using VCCT with quarter tip elements in Abaqus (not XFEM). I can solve the problem and get the SIFs.
How can I let the crack grow? Has someone a script for crack growth and remeshing that I can implement?

Hello to everybody,

 Can somebody help me with advice in the next problem : I want to study an dynamic movement of some beams, with rigid body option from ANSYS Classic. I encountered the problem when I want to choose the element type for cilynder. I choose LINK11. But I need to simulate what is happend between the moment when is applied the force on cilynder and imposed lenght of ciclynder after pool.

How I can settup the properties of element LINK11 to satisfy my results.
