When you interface COMSOL 3.5a with MATLAB 2009b or 2010a, some error messages may appear unless you have installed the latest software patch.

Linux and Windows error message examples

Running COMSOL 3.5a with MATLAB 2009b or 2010a gives the following output on the command line:

OMP abort: Initializing libguide.so, but found libiomp5.so already initialized. This may cause performance degradation and correctness issues. Set environment variable KMP_DUPLICATE_LIB_OK=TRUE to ignore this problem and force the program to continue anyway. Please note that the use of KMP_DUPLICATE_LIB_OK is unsupported and using it may cause undefined behavior. For more information, please contact Intel(R) Premier Support.

Mac OS X error message examples

If COMSOL 3.5a with MATLAB R2009b is started with the command

comsol matlab

64-bit MATLAB is launched, but with 32-bit COMSOL paths set.
The error message displayed in the MATLAB command window is:
