Dear Mr. Knepley,<br>
<br>
I would like to adapt our finite element code to use Sieve for distributed data management and as an interface to the PETSc solvers. Unfortunately the examples are currently broken, so I am having problems getting started. From the sieve-dev mailing list I could see that there is some development activity, however I am not sure if there is anything planned to be fixed or released that would be a starting point. Can you give me any additional information?<br>
</blockquote><div><br></div><div>Sure. Most examples are currently broken. I should probably take them out. The reason is that I spend all my</div><div>time supporting the specific needs of applications that use Sieve rather than the basics, like the examples. Not</div>
<div>optimal, but its only me so far.</div><div><br></div><div>So what hope is there of using it?</div><div><br></div><div> 1) There is an extensive tutorial about its integration with PETSc solvers (the first link in Previous):</div>
