Dear CFD people, I am trying to validate my laminar 2d finite volume -ROE FDS- solver using NACA0012. However, as I increased the number of grid point, I met the following error and couldn't fixed it. Can you please help me? Thanks. Regards.

Error I met:

forrtl: severe (170): Program Exception - stack overflow

Try to create a 64 bit object file so as to increase the memory allocation for arrays. I use the -64 compiler option for f77 on an SGI machine.

A stack overflow usually indicates that you have huge local arrays in a function or subroutine.

Try declaring your arrays as DATA or COMMON. This will take them off the stack.

Thanks a lot for valuable suggestions.

I modified the stack size in the executable itself using EDITBIN, such as: editbin /stack:4000000 main.exe

It worked

Regards.....

I think you did this in linux based system. right?

Is it possible to do in Windows-based fortran compilers like Lahey-Fhjitsu or Digitial Visual Fortran as well?

Thanks,
