Bug in batch mode version 6.3.9 of PVsyst?

[spelland74]

Hello,

I have been using the batch mode of PVsyst to run several meteo files for a project. With previous versions, this was working fine. In the current version, somehow PVsyst is running the first simulation in the batch twice instead of once, and doesn't do the last simulation. I have tried various solutions and been unable to fix this. I am giving an example of input batch parameters below (I have changed the files a bit to protect client privacy). In that example, when I run this batch file, the TMY gets simulated twice rather than once, and everything else is offset. The 2014 .met file does not get simulated.

Best regards,

Sophie

I have just downloaded again version 6.3.8 and can confirm that there is no issue running my simulation with the batch parameter file I showed in the previous post. The issue only occurs for 6.3.9, so I believe there is a bug in the 6.3.9 batch algorithms.

Yes, there seems to be something wrong there. I will look into it right now.

I also have had this problem, and welcome it getting resolved ASAP. Thanks!

I just updated to 6.41 and have found that the issue has changed. I run multiple meteo files, and run each meteo file with a change of a parameter.

Now when I run multiple meteo files in batch, the first run of a meteo file uses the correct meteo file, but the following runs use the first year I specified.

In fact the variants were not being properly restored after each batch run step.

This is now fixed for the coming version 6.42.

Thank you for reporting the issue.
