If I send this message from my 1st e-mail account i at tn-home.de I always get an answer from getdp-bounce at ...
Please, apologize in the event that against all expectations this e-mail arrives twice.

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 
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
