<div class="PlainText">Hi Neks,<br>
<br>
in order to use projection (p94!=0) for one temperature field and at <br>
least one additional passive scalar, I believe that the variables <br>
napproxt and approxt need to be extended by the size of ldimt. See the <br>
attached git-diff.txt for my changes to the code.<br>
<br>
When I adjust the code like that, projection for veloctity, temperature <br>
and all passive scalars works, otherwise it fails with:<br>

Can one of the developers please confirm and if confirmed include it in <br>
the master branch?<br>
