Adding variables causes odd issue
mikrom, I think you have hit upon what my target should be which is what is used for the rkm. A lot of the things you discuss here I was beginning to learn when I first started working on this program, but due to the long hiatus I am going to have to take some time to re-learn and beyond. In... -
Adding variables causes odd issue
xwb, I've suspected the rk method for a long time but keep coming back to the fact that an extra variable that is never used should not have any effect on it. I have noticed using different programs that the calculations simply go haywire at some point once I have more than 33 variables, but... -
Adding variables causes odd issue
Mikrom, Do you know if you got more than 1 line of values in your fort. files when you ran it using: g77 Fortran_kbk.f -o Fortran_kbk I tried using this command in cygwin xterm (x11) instead of make but it completes immediately w/ only one iteration of values. When I use the makefile and only... -
Adding variables causes odd issue
Hi mikrom and xwb, xwb, you're right about the concatenation issue. I fixed it and am currently running, but this a recent issue as I've had this right before and had the same issue, even after charactering out this equation and making = 0.0. mikrom, I never considered tweaking the makefile... -
Adding variables causes odd issue
Hi, I've copied all the main and subroutines all to a single text file that I uploaded to http://www.sendspace.com/file/0bnrye I hope that is an OK way to provide it. There is nothing proprietary in the code, but I still didn't want it just hanging around on the internet in its current state... -

Thanks! I'll clean it up and post ASAP. -K -
Adding variables causes odd issue
I am confident I am not going over 72 columns and have not misspelled anything Does hardcoding refer to the machine language used in cygwin or the fortran compiler I use in my cygwin version? Maybe something w/ my computer or OS? I have tried running the code in Salford Plato software which is... -
Adding variables causes odd issue
I believe so, the beginning of the main routine is as follows: implicit double precision (a-h,o-z) parameter(neq=34,nflux=25,nstepmax=10000) dimension y(neq),dy(neq) dimension flux(nflux) neq has been changed from less than 30 up to 44 in the past and it never works... -
Adding variables causes odd issue
Hi, I've been stuck on a project for about 3 years and it has really stalled my hopes of becoming an adequate programmer. Any help would be so appreciated! In short, when I have 33 variables y(1) through y(33) the code runs great. However, once I add in a 34th variable y(34) the code does...
