Ok, thank you Davis. Best regards, Tiago Abud

Hello, In the manual of OpenDSS version 9.1.3.2 there is a chapter related to OpenDSS-GIS. So, I was wondering if OpenDSS-GIS is already available for download and how I could install it. Also, I would like to know if OpenDSS-GIS package come with OpenDSS, or with OpenDSS-G, or it is a different software and we need to install it separately. Currently, I am only using OpenDSS, and not OpenDSS-G. Do I need to install OpenDSS-G to use OpenDSS-GIS? Thank you for your time, Tiago Abud

Hello, Davis. I wrote the "ClearAll" command before reloading the dss code, but some simulations are still presenting the error 423. So, I tried to install an old OpenDSS version (7.6.5.52) I used years ago to work with a similar code. And fortunately, I ran thousands of simulations without presenting any error. Therefore, I think the error is totally fixed this time. Hope this conclusion can help us to understand what is happening. Best regards, Tiago

Hello, Davis. Thanks for the explanations about the error. I am not using virtual machine. But I am using COM interface, via Excel VBA. I wrote the "ClearAll" command before reloading the dss code. I will run thousands of simulations to test if the error is still occurring. Tomorrow, I'll let you know if this solved the error. Thank you for the support. Tiago

Hello Davis, Thanks for your prompt reply once again. Answering your questions: No, I am not using parallel processing. On each simulation, I reload the dss files and run OpenDSS. I thought it would not be a problem as the dss code starts with "clear" command. What do you think? Should I do anything else to clear the memory? Or should I not reload the files? The objective of this program is to carry out a Monte Carlo simulation to analyze photovoltaic distributed generation impacts on LV network,...

Hello Davis, Thanks for your reply. I would like to share my code, but I am afraid it is too large and has lots of VBA routines. So, it may take a long time to be understood. I don't know what may cause this kind of error. If there is an specific part of the code that could be causing this error, please tell me that I will post here this part. What the code does is running a Monte Carlo simulation, generating random variables at each simulation via VBA and then running OpenDSS files considering the...

Hello again, I thought this error was solved. However, some of the simulations are still presenting the same error. Note that it rarely occurs (maybe 1 simulation out of 100), that is why I thought it was solved. Besides, this error (423) is sometimes occuring regarding elements other than EnergyMeter, such as "Exception Freeing Circuit Element: Transformer.(...)" and " Exception Freeing Circuit Element: load.(...)". I've installed the latest version (8.6.7.1), downloaded and replaced the files Opendss.exe...
