[Getdp] Two parallel uncoupled systems

Hello,
in acoustics-transmissionPars.pro there are two boundary value problems defined
which are actually coupled.
One of these is hyperbolic and one is parabolic. I wanted to do a frequency
analysis of the coupled problem.
It did not work.
For diagnosis, I decoupled the problems by commenting out the coupling code
blocks by one-line comments "\\".
The combined model with the two decoupled problems does also not run. Solve[sys]
does not work.

Thereafter, I created two models (a-p.pro and a-pF.pro). In each of the models I
commented out one of the problems.
This is possible since both problems are well-separated. Both models run fine
and give the expected results.

I am using the current stable release of gmsh2.6.1 and getdp2.2.1. (both: 32-bit
version)
The specs of my computer are:

CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40 GHz 3.40 GHz
Memory: 8GB
System Type: 64 Bit

The output of gmsh for acoustics-transmissionPars.pro is attached as file "log"
to this message.

It would be nice if these problems could be solved until tomorrow. (It would be
very nice to have the results on Monday.)

Thanks in advance for a fast answer.

Nevertheless, I know that I cannot put any kind of pressure on you. If a
solution is only later available I would like to konw the reason of the failure
anyway.

Best regards,
Tobias Naehring
