The issue occurs in the xp2/xpyp "upwind" turbulent advection code and involves the "sgn_" variables. Ultimately, for other PDFs, I was setting this variable using equations of the form sign( one, variable) which set the value to either 1 or -1 no matter the value of variable. However, for the ADG1 PDF, I was lazy and simply just set the value of sgn_ to be equal to wp3_on_wp2. The issue arose when wp3_on_wp2 had a value of 0, and therefore is neither negative or positive. To rectifiy the issue, all settings of "sgn_" variables now use equations of the form sign( one, variable ). For a vast majority of cases, this change had absolutely no effect on the results and everything stayed bit-for-bit. However, BIT_CHANGING results were detected for CGILS S6, MC3E, and TWP-ICE. 2024-11-11 11:50:40 -06000c81e032e7c8627c963780496471ffda1f533007As part of generalizing the code to work with both an ascending andeditadvance_xp2_xpyp_module.F90githttp://carson.math.uwm.edu/jenkins/user/bmg2bmg2false437http://carson.math.uwm.edu/jenkins/job/cam_scam_gfortran_debug_test/437/435http://carson.math.uwm.edu/jenkins/job/cam_scam_gfortran_debug_test/435/
