Error during writing output file

[Sushmitharao46]

Hi,
I'm getting the following error sometimes when the code reaches the time step=ioutput.
Note: The following floating-point exceptions are signalling: IEEE_DIVIDE_BY_ZERO IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
ERROR in MPI_FILE_WRITE_ALL
Can someone please comment why this error is showing up.
Thank you.

Hello,

Are you using a modified version of the code ? What kind of flow are you simulating ? What is your input file ? What is the compiler used ? What is the MPI library ? What is the file producing the error ? Can you reproduce the error on another machine ?

Your message is very vague.

Regards,

Yes I've modified some of the ALM part of the code. I've attached the input file. I've used intel 2019 compiler. Yes I'm getting this error in some of the cases.
