Hi, everyone

I have read the mail list about meshdata structure, I want to confirm whether new nodes and elements can be updated (that is, be inserted?) and the data associated with new/old nodes and elements in meshdata can't be updated after mesh refinement?  In addition, if I use other file formats but xda, unv and tetgen, how should I do to use meshdata? Different mesh file formats only means different methods to read mesh data?

Thanks a lot.
