I am currently trying to compile a finite element program with user code that was perviously compiled with CVF 6.5. However, the results from the analysis using IVF are significantly different due to the number of loops and, I assume, small differences in the numbers. I no longer have access to CVF and only have the source files and the previously compiled executable to use to compare results. I have tried disabling optimzation, /arch:IA32, /Qsave, /fp:source, /assume:protect_parens, and every combination of the above all having no effect on the results that I am getting. I am a civil engineer by trade, but I have examined this code over and over and I have had no success in determining what is causing this issue. The code is written in fortran90. Any thoughts or ideas on where this error could be coming from or other compiler options I should try? I have read through forum after forum and they all say try the options I have listed above; I am at a loss of how to proceed.
