[Libmesh-users] where can I find the definition for xda file?

[seid m. b. n. <mbo...@ya...>]

Hi
I ran the ex1 example and I have some questions.
I am sorry to ask too much.
The one_quad.xda file have some parameters that I
could not understand them.they are as follows:
what does "Num. Element Blocks" mean?
what does Element types in each block mean?(actually
where can I find the definition of Element types for
example quad=5)
There is a line "0 1 2 3" in this file,what does it
mean?
There is an extra column after the coordinates,is it
used for marking for boundary conditions?(if yes where
can I find the definition of boundary conditions and
their appropriate values?)
In the last part there are some numbers.Is it possible
let me know the definition of them?
0 0 0
0 1 1
0 2 2
0 3 3

I look forward to hearing from you

Best Regard

Bostandoost
