Hi,
I am trying to implement a 3-D Surface Registration code using PetSc. I
want to create a vector of structures i.e.
struct Point {
double x, y, z;
};
Then create a PetSc vector that stores array of "Points types". Can
someone point me to the right direction.
regards

It turns out the machine's Linux/glibc versions are too old. The configure
passed the error after I switched to a new machine.
Thanks a lot,
Qin

Dear All:
I am solving a series of matrix which are from the same FEA model but have
different number of meshes. In petsc, I use CR as the solver and
hypre-boomeramg as the preconditioner. It works for a small system with 2
million DOFs. Also works for a system with 6 million DOFs. But always fail
Hi,
I'm trying to write a fortran code that uses TS with DMComposite for a
multiphysics problem. How can I access local vectors created using a
DMCreateGlobalVector() from a Fortran code? I tried
DMCompositeGetLocalVectorsF90(), but I believe there isn't such a function.
Also, what is the differe

Thanks a lot. I did what you told.
It is working now like a charm.
However, I have another query, which I will post separately.

Ok. I am doing the following
1. Running "./ex7 -f1 A2 -f2 B2 -st_type sinvert -evecs VC"
2. In MATLAB I do "vc=PetscBinaryRead('VC');"
The output is one Eigenvector in VC which is 800x1.
And I did the normalization vc=vc/max(vc) and compared with the normalized
original vector.. Also I must tell

It works for me, so you should provide more det
