Summary0001575: Regex issue in tutorials/multiphase/twoPhaseEulerFoam/RAS/bubbleColumn/
DescriptionI am getting the following exception when running icoFoam against $FOAM_RUN/tutorials/multiphase/twoPhaseEulerFoam/RAS/bubbleColumn/ :

   Failed to compile regular expression 'div\(\(\(\(alpha.**thermo:rho.*\)*nuEff.*\)*dev2\(T\(grad\(U.*\)\)\)\)\)'
   repetition-operator operand invalid

       From function regExp::set(const char*)
       in file regExp.C at line 93.

   FOAM exiting

There appears to be an extra asterisk or one that isn't escaped, in system/fvSchemes
TagsNo tags attached.

I am unable to reproduce this problem on GNU/Linux (OpenSuSE 13.1) so there seems to be a difference in the regex library you are using. Which OS are you running on?

Try escaping the second * in the "alpha.**", i.e." alpha.*\*"

If this works OK I will change all the occurrences in the tutorials

This was on MacOS X and another user on the platform suggested that he worked around the issue by escaping the second star. I haven't been able to check this on a Linux based host to compare, as of yet.
