<div>Hi,</div>
<div><br>
</div>
Good to hear open boundaries are on the list. Do you perhaps have any idea of a time frame for this?
<div><br>
</div>
<div>I've attached the paper again just in case.</div>
<div><br>
</div>
<div>@ Thomas, yes, I'd like a plate coming in at the boundaries.</div>
<div><br>
</div>
<div>Thank you all,</div>

This has been on my list for a long time, but it's nontrivial for the reasons Thomas pointed out...<br>

The paper Anne attached got lost off-list. Can anyone put a entry into the TODO list with a reference to this paper?<br>
