[petsc-users] Using PETSc to read/manipulate mesh files

[Aroli Marcellinus]

Dear all,

I have this kind of mesh file, and I want to use PETSc to include the
information of this file.


In short, this file contains of:

<NUM_OF_NODES> <NUM_OF_ELEMENTS> <1> <2> <3>
<NODE1_X_COORD>  <NODE1_Y_COORD> <NODE1_Z_COORD> <FLAG>
<NODE2_X_COORD>  <NODE2_Y_COORD> <NODE2_Z_COORD> <FLAG>
<NODE3_X_COORD>  <NODE3_Y_COORD> <NODE3_Z_COORD> <FLAG>
...
...
...
<NODEN_X_COORD>  <NODEN_Y_COORD> <NODEN_Z_COORD> <FLAG>
<ELEMENT_NUMBER_1> <ELEMENT_NUMBER_2> <ELEMENT_NUMBER_3> <ELEMENT_NUMBER_4>
<----showing element connectivity from node 1 2 3 and 4.

Can I read this kind of data into PETSc? I am new in PETSc and want to use
it for this purpose.


Actually, this file contains a mesh of cardiac heart, and I want to convert
this data into a suitable mesh data structure, and I thought that PETSc
have a kind of mesh data structure. However, after surfing into a lot of
tutorial, I cannot find any references that suits my purpose.
