I am a PhD student at Alexandria University, Egypt and my thesis topic is related to the simulation of IWA's activated sludge models. I've developed a basic simulator using MATLAB that adopts a predefined activated sludge scheme -the COST benchmark case study- to simulate models ASM1, ASM2d and ASM3. First to simulate steady state, then using dynamic influent files (text files) representative of different weather conditions and diurnal variation in influent flow. As I am currently trying to verify the results of this application, I downloaded a demo version of ASIM 4.0, to see whether I can simulate the COST benchmark case study with ASIM 4.0, then compare results of my application with those obtained when ASIM 4.0 is used. For a start it seems that this implementation isn't completely straightforward, as ASIM 4.0 uses a specific format (*.vrt) for dynamic input files termed variation files. I would like to know whether there is a way to make ASIM realizes *.txt files or to introduce my data files to ASIM 4.0 forms by converting text files to variation files. I tried (copy/paste) to ASIM 4.0 forms but all the copied records were placed in one cell triggering an error message as a result.
concerning your question about import of text files to variation: - the variation file is a text file. The format is described in the attached html file - you can copy and paste variation form columns from the clipboard. Please have a look in the online help under the topic How to / Copy variation values....
Thank you very much for answering my e-mail and for the clarification and the attached file. I've followed the instructions of the online help regarding copying variation file from the clipboard. However, it seems that in the demo version, the combo box entitled "copy file from" does not provide the clipboard as an option. Thank you again for your help.
Copying should work with the demo version. In order to activate the item 'from clipboard' you have to copy the values from the application (Excel,Word,Notepad) to the clipboard. I tested it with Excel, Word and Notepad and it worked fine: - first select the values in Excel which you want to copy to ASIM (the values can be in rows or columns) - choose 'Edit / Copy' or Ctrl-C in Excel - then switch to ASIM (let Excel open) - in the variation form click on the column header of the column where you want to paste the values - from the combobox choose the last item 'from Clipboard' (maybe it would be better to add this as first item) - then the values should be copied to the column - it is not possible to copy and paste multiple columns
Thank you very much for the clarification and my apologies that you had to provide this detailed explanation. I've tried it hurriedly Yesterday using Excel and I didn't realize then that this option appears only -as should be- when there is something in the clipboard to be pasted. I think what made the (from clipboard) option not to appear to me is that I opened the combo-box before copying from Excel. i.e. the combo box should have been re-opened after the copy process. Thank you again for your concern.
