Hello,
I'm getting some slight differences in some of my coefficients when comparing FiPy to Fortran benchmark code I'm using. I have confirmed that the equations are the same. There are some other potential areas that may be responsible for the discrepency, but I wonder if it may be due to precision.
I'm using Double Precision in the fortran code, and for any numbers in FiPy I am ending them in a decimal point and zero if it does not have values after the decimal, and of course anything that does have values after the decimal are input as such.
Is it reasonable to think that my descrepencies are due to precision? If so, do you have suggestions of how to reduce/eliminate the descrepancy?
Thanks
Buddy
