*** glibc detected ***
 
Hi All,

I've been using my own post-processing utility (named modeFFTuwS) for a while without trouble or bug. Now that I've changed my boundary condition, and only that, (I went from one periodic face pair to two periodic face pairs) this post-processing utility crash every time. The simulation went well. I have a very long error message beginning by :

Quote:

*** glibc detected *** modeFFTuwS: free(): invalid next size (normal): 0x000000001869dd30 ***

P.S. : If I reduce the size of my mesh no error occurs...
P.P.S : Error occurs only on parallel calculation.

Thank you very much for the help!
