The
following changes were made since version 7.0 was released. For changes
made prior to version 7.0, see What's New
in Version 7.0.
New Features
-
Additional example models have been added to the Examples folder
and a new "How Do I" folder contains models illustrating how to
accomplish useful tasks in Berkeley Madonna. Models in these folders
can be opened using the "Examples" and "How Do I" submenus in
the Help menu.
-
The POISSON built-in function generates random deviates
from a Poisson distribution.
-
The CONVEYOR built-in function delays input values by
a variable "transit time" assigned when the input is placed on
the conveyor. The result is the sum of all elements whose transit
times have expired. This function can be used in combination with
a differential equation to duplicate the effect of STELLA conveyors.
Flowchart Improvements
-
The thick lines connecting a flow icon to its source and sink
(known as "pipes") can be precisely positioned by clicking on
the pipe and dragging one of the square handles (similar to positioning
arcs).
-
A reservoir can be moved into a submodel while the flow to which
it is attached remains in the parent model. This capability makes
it easier to organize complex models.
-
Reservoir initializers that depend on other symbols in your model
require arcs from these symbols to the reservoir. Requiring these
dependencies to be explicitly indicated makes it possible for
the program to guarantee that the generated equations are valid.
Existing models with these dependencies will need to be modified
by adding the necessary arcs.
-
Icon graphics have been improved. In particular, alias icons look
a lot better than they used to.
Important:
Due to the above changes, flowchart models saved in version 7.0.2
cannot be opened by previous versions of Berkeley Madonna.
Bug
Fixes
-
The program crashes when opening the Batch Runs dialog
for a model saved in Madonna 6.0 with the run mode set to "Parametric
Run".
- DTMIN
is not verified to be positive before running the model with a
variable-stepsize integration method.
-
Value of DT may influence output of the DELAY
built-in function when using a variable-stepsize integration method.
-
Datasets are removed from a graph window when running model and
no model variables are plotted in that window.
-
Clouds may not be hidden when their connecting flows are hidden.
-
[Macintosh only] Long window captions can cause menus to malfunction
and possibly crash the program. This is most likely to occur with
graph windows plotting many variables.
-
[Macintosh only] Program would hang when choosing the "Icon Info"
for a standalone text label.
-
[Windows only] The program hangs for five seconds while exiting
when the Equation Help window is left open.
-
Chemical reaction terms beginning with a number followed by the
letter E are parsed incorrectly. For example, the term "2ES" is
parsed as "2S".
