Dear All,<br>
<br>
I'm pretty new to the Petsc library, before going into installation hassle,<br>
I'd like to know is it possible solve common eigenvalue problems mainly <br>
encountered in solid mechanics engineering such as Subspace iteration,Jacobi <br>
method, simultaneous iteration, Stodola etc..with Petsc.<br></blockquote><div><br></div><div style>SLEPc is the eigensolver package build on PETSc.</div><div><br></div><div><a href="http://www.grycap.upv.es/slepc/">http://www.grycap.upv.es/slepc/</a><br>

Mainly those problems comes in stiffness and mass matrices form, where in general <br>
they are symmetric and can be huge in size e.g 5000x5000.<br>
<br>
If it's possible to solve those type of problems with Petsc then is it <br>
trouble free the installation of library with Gnu GCC and gfortran on Win64?<br></blockquote><div><br></div><div style>Cygwin is required to build PETSc, but not to use it.</div></div></div></div>
