Dear MUG,
In running my model (7 ODEs) using DEplot, I sometimes get the error message
"Stopping integration due to, undefined", depending on the parameter values
used. In some cases, decreasing the stepsize gives indeed the desired plot.
COULD the size of the stepsize BE the reason for the error message?
In other cases I have to decrease the stepsize so much that my computer
crashes (no simulation succeeded for stepsize=0.0001 and t=0..500). My
computer is a Pentium 794MHz, 128 Mb RAM. Is it possible to write the points
that are calculated by DEplot to a file, such that after each time step the
value for each variable is written to a file? If the computer gets stuck in a
particular run, then at least the points until the crash are available, which
may provide information on the cause of the crash.
Thanks for any advice, best wishes,
