[petsc-users] DMNetwork usage example

[Dharmendar Reddy]

Hello,
           I have a few question regarding the usage.

In DMNetworkRegisterComponent(DM dm,const char *name,PetscInt size,PetscInt
*key)
* size *- the storage size in bytes for this component data

If i call it from fortran, is size then the number of components ?

For example, if i have a network of nodes, I want to store the location of
the node ( double precision :: x,y,z) in the component named "position",
then is the call:


call DMNetworkRegisterComponent(DM dm,"position", 3, positionkey, ierr)

I need to create a network. I know the number of nodes on network and the
maximum number of neighbors any node can have. I can only add the node to
node connections as few at a time.

Is this possible to do with DMNetowrk ?
