Upgrade to ASIM Windows Version 4.0.3.1
Download and installation instructions:
 
Download the self-extracting Installation file of the demo version to a local temporary directory
To install the demo version you need the password that you have gotten by e-mail
Run the file in the temporary directory by double-clicking on it
Follow the instructions of the setup program
If the old version was not registered or after a new installation the program will run in demo mode
To run the program in normal mode you have to purchase a license
Send an e-mail to asim@eawag.ch to order a license
If you have purchased a license we will send you a license key by e-mail
Please enter the license key by choosing Tools / Register and restart the program
 
Please note:
It is not necessary to uninstall an older version of ASIM. You can install to the same directory, older files are automatically overwritten, the registration will not be removed and user created ASIM files will not be deleted
If you install the new version to a different directory, the old version is not removed and you have to register the new version with the same user name and key than the old one. Then you can use both versions.
Warning! If you uninstall a registered old version and install the new one you have to register the new version again by entering user name and license key!


 New in this version:
SBR: number of periods increased from 12 to 48
Maximal number of plot points is set to 1440 (before 288)
Log file asim.log is now saved in user directory, not anymore in program directory (changed because of user right problems)
Bugfix: no access violation if an AI project is loaded over a non-AI project
Bugfix: loading of a variation file is only possible when a plant is loaded
Bugfix: autosizing of column widths did not work for the first display. You had to display the grid again for correct autosizing. That is fixed now.


Changes in version 4.0.2.4:
Allowed number of reactors changed from 12 to 18
Allowed number of points in a cycle changed from 96 to 288 (for variation and SBR)
A/I module implemented (you need a separate license for this module, please contact Manfred Tschui from Holinger AG for additional information)
 
Fixed bugs in version 4.0.0.4:
Project listing in "Choose project" improved. Project listing was in some cases incorrect.
ActiveX component for control loops is replaced by normal component integrated in the program => no more registration of an ActiveX component in the registry database
 
Fixed bugs in version 4.0.0.2:
Some processes (Exponential, Monod II, Inhibition II, Gas stripping II and III) for dissolved species worked wrong
If the user directory was changed, its name was not saved in the ini-file
Online-Upgrade was not possible from domains outside ETHZ
If number of reactors was changed, values of O2-Setpoint and kla were not cleared for clarifiers
Data series of 2. influent could not be chosen in 'Add series to chart'
No popup menu in table 'Reactors and secondary clarifiers' of form 'Flowscheme'
If control loops were activated, O2-Setpoint had to be set to zero to activate control of kla values
If variation window is shown no other window can be selected. Now other windows can be simultaneously opened
It was possible to run more than one instance of ASIM
 
Known bugs of this and older versions:
Column widths in tables are sometimes too small (Column labels are sometimes truncated). Workaround: Switch to an other tab and then  back. If the tab is selected a second time then column widths are correct. Should be fixed since version 4.0.3.1
Variation / Edit Variation: Field "Load" of dissolved and particulate species is editable, should be locked
Variation / temperature: values cannot be copied from other columns or from clipboard
Model / Edit active Model: If you click in most right fields of "Kinetics" tables which are partly hidden, table will be scrolled and cursor will be placed in a wrong field. Combobox may be incorrectly positioned (Workaround: Scroll the table first and then click in the field)
Calculation of pH is not yet implemented
Decimal separator should be a point (.). If decimal separator is set to comma in your operating system (Windows), ASIM will run anyway but will use a point as decimal separator. You will have problems to cut and paste numbers from ASIM to e.g. Excel or others applications using the default decimal separator settings of Windows
Bug list is not complete :-( and will be continued :-)
