How to curve quadratic elements
How to curve quadratic elements
(OP)
Hello,
I'm having trouble in meshing a plane model using quadratic shell elements in Abaqus CAE. I have to model a quarter of circle and I want the elements on the border to be perfectly coincident with the external circumference. However the mesh created by Abaqus has just the nodes on the circumference with straight lines connecting them. How can I curve the elements to match all the circumference?
Thanks

You can use the, mesh > edit, function and project the nodes to the geometry, boring!

I can understand a p-method based fem computing the boundary curve from the element shape functions for display purposes, but I am not aware of any h-method fem (like Abaqus) using anything other than straight lines between the nodes of an element in a display.
What are these "other fem softwares" that do?

However Strand7 uses the old windows GDI graphics system, whereas Abaqus/CAE (along with all other vendors except Strand7 !) use OpenGL graphics. I know which I would rather use.

No, you will not be able to do this. You either go back to Straus7 or write your own software to do this.
