Description
User Guoyan (gyjiang@whu.edu.cn) encountered “stack overflow” problem when running a THM simulation using node count of 154395, same problem runs fine with node count of 52269. The simulation was carried out on a Windows 10 64-bit machine, with six installed memory sticks of DDR4 2933MHz 32GB, FEHM executable used is Version 3.4.0
Possible fix from George Zyvoloski: use trace back information, taking the array out of a subroutine call header and put the variable into a use module.

Research direction
Start by reproducing the FEHM 3.4.0 simulation on Windows with 52,269 and 154,395 nodes, then collect trace-back information for the stack overflow. Inspect the subroutine call headers and the related use modules, as suggested in the issue. Done means the larger simulation runs without the stack overflow.
