Hi Neks,

in order to use projection (p94!=0) for one temperature field and at 
least one additional passive scalar, I believe that the variables 
napproxt and approxt need to be extended by the size of ldimt. See the 
attached git-diff.txt for my changes to the code.

When I adjust the code like that, projection for veloctity, temperature 
and all passive scalars works, otherwise it fails with:

...
22  Error Hmholtz TEMP     100          NaN          NaN 1.0000E-08
22proj_ortho:    1   2 TEMP   Detect rank deficiency: NaN         NaN
22  Project PS 1                  NaN          NaN          NaN 1   0
22  Error Hmholtz PS 1     100          NaN          NaN 1.0000E-08
22proj_ortho:    1   2 PS 1   Detect rank deficiency: NaN         NaN
22  Project PS 2                  NaN          NaN          NaN 1   0
22  Error Hmholtz PS 2     100          NaN          NaN 1.0000E-08
22proj_ortho:    1   2 PS 2   Detect rank deficiency: NaN         NaN
...

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


Best,
Steffen Straub
