Error Message "Stopped in Routine SIG_HANDLER" appears starting CFX-Solver
 

Hi,

starting my project in CFX-Solver the following Message appears in the Out-file befor starting any Iteration:

Does anybody have an idea what the problem might be, or rather what the routine SIG_HANDLER is responsible for?

Dear
Niklas

Proably just a missing parameter you forgot to set on Ansys.
These two links might help:

You should confirm correct operation of your hardware with benchmarking software. I use pcwizad 2009, by cpud..its free. Look at your power supply voltages..12v..5v..3.3v..they should be within 5-10% of spec.

Also look at your cpu temperature and video card temps..these can cause errors. Add fans if neccessary.
Incorrect driver on an ethernet card can cause Linux kernal panic.

You should be running a fairly powerful computer..dual or quad core with 4 gb memory..a single core system thats overloaded can give errors. A video card with at least 512 mb.

Did you correctly set all of the parameters of Ansys correctly?
Update your Linux package dependencies if neccessary and practcal. You may be limited by your kernal version number.

Ansys was probably written in C++, and Linux in C (Unix most likely). I did not find that error code in C++ MSDN docs from 2003 msdn library.

SIG_HANDLER is most likely a Unix command. Handles timeout event. Maybe the program did not get info from a module that was not loaded, that was supposed to be loaded..or the system hung because the solver was overwhelmed by the complexity of the problem with respect to computer capabilities. See: http://www.theaceorb.com/1.3a/doxygen/ace/classACE__Event__Handler__T.html

Looks like the program is loading about 990mb of ram for this solver. It appears to be loading a mesh also. Is your video card memory big eneough for the mesh? System memory adequate?
What are your system specs..ram..cpu..OS..video..ethernet..Linux Kernal version..any other programs running?..run antivirus recently? adaware? ..defraghard drive recently? Strange errors are seen in very demanding programs and models due to limitations of hardware usually..ie cpu speed, number of cores. memory ..ect..

I dont have Ansys, I use Elmer and OpenFoam and SciLab.

good luck!!

Hi Andy,

thank you very much for your detailed answer. I will work off your list of suggestions.

kind regards
Niklas

I don't think Andy is sending you down the right track though. Quite simply it crashed when it started coupled partitioning. I don't think the multi-processor stuff is set up correctly on your machine. Have you followed the setup instructions in the setup manual? Does serial simulation work? Does normal single threaded partitioning work?

Hi ghorrocks,

i´m computing on a cluster-system, so i have no influence on the hardware-software setup. But i brought to light that currently there is a technical problem on the cluster-system at least on the Unix-Frontend. So i started my project on the Windows-Frontend, and voila the solver started.
Thank you verry much for your tipps;)

bye

SIG_HANDLER problem
 

hello, I am having the same problem as mentioned but I do not find a way to solve it. I am using a cluster but this is the first time that I have this problem. can you give me hint what it is happening and how to fix it?

Hi to all

I've faced this problem recently. The mesh was big - 30M nodes and 75M elements. The solution for me was relatively simple - involving 12 cpu cores and activating large problem option (8 cores without large problem option yielded the same error).
