Floating-Point Exception Errors When Running Inlet Refined Test in COAWST 3.8

[Pbarbosa92]

I'm trying to compile and run COAWST (version 3.8) for the Inlet Refined test, but I’m encountering errors during execution.

Observed Behavior

1. Initially, I receive the following warning:

   MCT::m_MCTWorld::initm_MCTERROR:  MCTWorld has already been initialized...Continuing  
   MCT::m_MCTWorld::initm_MCTERROR:  MCTWorld has already been initialized...Continuing  
   

2. After some time, the simulation prints this erros (but continues):

   Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DIVIDE_BY_ZERO IEEE_UNDERFLOW_FLAG  
   Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG  
   

Steps Taken

I compiled COAWST and its dependencies following the standard procedure:

• Built SCRIP_COAWST
• Compiled mct
• Installed mct
• Ran the build_inlet_refined.sh script
• Executed the simulation with:

  mpirun -np 2 coawstM Projects/Inlet_test/Refined/coupling_inlet_test_ref3.in  

Logs and Build Files

For reference, here are the relevant logs and scripts:

• COAWST SCRIPT Make Output: coawst_make.txt
• MCT Make Output: mct_make.txt
• MCT Install Log: mct_make_install.txt
• Build Script: build_inlet_refined_script.txt
• Build Output: build_inlet_refined.txt
• run the simulation with mpirun -np 2 coawstM Projects/Inlet_test/Refined/coupling_inlet_test_ref3.in

Has anyone encountered similar issues? Any guidance would be greatly appreciated!

Thanks in advance for your help.

those are just warnings. i see them all the time.
1 the MCT init comes up because the 2nd grid goes to init and MCT says we did this already. so it is ok. just a warning.
2 the IEEE floating is just another warning. I dont think it is a problem.

suggest you just keep moving forward!
let me know if have any other issues.
