I wanted to do a frequency <br>analysis of the coupled problem. <br>It did not work. <br>For diagnosis, I decoupled the problems by commenting out the coupling code <br>blocks by one-line comments "\\". <br>The combined model with the two decoupled problems does also not run. Solve[sys] <br>does not work. <br><br>Thereafter, I created two models (a-p.pro and a-pF.pro). In each of the models I <br>commented out one of the problems. <br>This is possible since both problems are well-separated. Both models run fine <br>and give the expected results. <br><br>I am using the current stable release of gmsh2.6.1 and getdp2.2.1. (both: 32-bit <br>version) <br>The specs of my computer are: <br><br>CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40 GHz 3.40 GHz <br>Memory: 8GB <br>System Type: 64 Bit <br><br>The output of gmsh for acoustics-transmissionPars.pro is attached as file "log" <br>to this message. <br><br>It would be nice if these problems could be solved until tomorrow. (It would be <br>very nice to have the results on Monday.) <br><br>Thanks in advance for a fast answer. <br><br>Nevertheless, I know that I cannot put any kind of pressure on you. If a <br>solution is only later available I would like to konw the reason of the failure <br>anyway. <br><br>Best regards, <br>Tobias Naehring</span><span lang=EN-US
