The best way to get into PETSc is by studying the example codes provided in the source tree. As a precursor to studying fortran examples, you should take a look at this page and decided which PETSc-fortran approach you wish to use: http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Sys/UsingFortran.html Thanks, Dave > Thanks, > > Matt > > On Thu, Mar 16, 2017 at 12:37 AM, Валентин Егоров < > egorow.walen...@gmail.com> wrote: > > Hello! > My name is Valentin Egorov.
