Dear all
I am running a fortran code for dns flow over a cylinder.
After some hundred iterations it gives an error
Note: The following floating-point exceptions are signalling: IEEE_DENORMAL
Can some one guide me how to adress it.
Thanks in advance.

have you checked the code using before debugging options? such options during the run can provide infos in case of errors. Furthermore, check also the array bound options and run the code without velocity optimizations

check the instructions of your compiler options, generally -O(n), -unroll, etc. are some of the options you should disable in the debugging
