Hello, I want to close the PETSc environment in the middle of my C program but want to retain the matrices generated in PETSc and access them using C program. How can i /(Can I) do this?
To be precise, i am solving eigenvalue system using SLEPc and i am using the results to decouple the system matrices. Now i want to run the Newmark integration code on those matrices. I am getting very slow performance by PETSc routines such as MatGetColumnVector() VecGetArray() MatAXPY() VecAXPBYPCZ() So i just want to close the PETSc environment and retain these matrices and solve using available Newmark code in C using mpi. Need your inputs. Thank you very much *Siddhesh M Godbole* 5th year Dual Degree, Civil Eng & Applied Mech. IIT Madras
