2. Macros - You can now perform a series of calculations (i.e. I-V curves) and examine the
results. There is also a large potential for bugs in this area. The only macro available is the
voltage macro where the applied contact potential is changed. Different kinds of macros (i.e.
temperature, input optical frequency, input optical intensity) will appear in later versions.
3. Band gap and thermal conductivity - These two parameters are now temperature
dependent. The material.prm file has been expanded to allow values to be varied which controls
the dependence of these parameters on temperature.
4. Lateral Heat flow - My model for lateral heat flow now has a user interface. This models
assumes that the device is cylindrical (with a specified radius) and the environment temperature
surrounds the device in a cylindrical geometry. Heat flow is calculated in the direction along
the device as well as laterally out to the environment. This option can of course be turned off.
5. Contacts and Surfaces - The contacts dialog box has been split into contacts and surfaces.
This will allow the future feature of having contacts that are not necessarily at the same location
as the device surface.
6. Freeze Plot - Plots can be "frozen" and "melted". When a plot is frozen, the data is not
updated when the state of the device changes. This allows data for two different device states
to be compared. When the plot is melted the data is updated to reflect the current device state.
7. Plot Parameters - Any positionally dependent variable can now be plotted.
8. Write Parameters - Any combination of parameters can be now be written to a disk file.
9. Operation - There are a number of subtle changes in the operation of SimWindows. For
instance if the environment temperature is changed, the state of the device is no longer reset to
the initial solution. It just needs to be resimulated in the present state.
10. User Manual - Included on the distribution disks is a postscript file of the present User
Manual. It is not complete yet, but the finished sections are included.
11. Windows NT - SimWindows will now run on Windows NT.

State Files are incompatible with older versions
1. Bug fixes: Version 1.0.2 is basically to fix a couple of bugs. Note that
version 1.0.1 was never released because I discovered a virus on my system at about the
time I was ready to release version 1.0.1. The bugs that were fixed over v. 1.0 are:
a. New parameters entered in the laser dialog box are used in subsequent calculations.
b. SimWindows works correctly on systems where the background window color is set
to a non-white color.
c. SimWindows tended to crash if more than 4 plots were opened and subsequent iterations were
performed. This has been corrected.
