Re: PETSc support for second-order elements?

1) The library is not mature. It is alpha. However, it is being used for
   several projects.

2) The PCICE reader is just an example. Other formats could be easily
    implemented.

3) I am not sure I understand your question about quadratic elements. We
   do support higher order elements (see the Tutorial on the website). This
   has nothing to do with geometry, and thus you would just read in a tet mesh.

 Thanks,

Hi there,

I am learning the PETSc tools provided in the latest
version to deal with unstructured grid. I realize that
with functions such as
MeshCreatePCICE(MeshCreatePyLith), we can load the
mesh directly from files, in the PCICE (PyLith)
format. This is really a great news for us.

However, we need to use second order elements, for
example, 10-node tetrahedra. I tried to load it with
MeshCreatePCICE but it seems to me that second order
elements are not yet supported. I've learned this from
the PyLith website also.

I want to ask is there a plan to support second order
elements? Roughly when would it be available?
Also if someone can comment on how mature the current
unstructured mesh library is, I would greatly
appreciate it.

Thank you for your help.
Shi
