Just a short question. Can I only use Initial condition of uniform
value instead of *.ini files. What is the impact of numerical result
if I use initial condition with uniform value compared to using *.ini file?
Thanks in advance
In general - within the sort of problems we solve with Delft3D - you
do not want the initial conditions to influence the result over the
long run. The initial condition is mostly a nuisance, especially if
you have a tidal flow or some other form of external forcing. (It is
different if you want to model a transient phenomenon like a dam break
or a tsunami). For a parameter like the water level, the transient
part dies out within a few tidal cycles. For salinity and temperature
this is likely to take much longer.
That said, the numerical difference between a uniform value and a
value that may vary over space is of impact only during the time of transition.
Dear Arjen Markus
Thank you for your reply. Nice answer.
