Getting the above error when trying to run this simulation. Version 2.20 build 74. Thanks.

Hi,

I've tried the sample file on V 2.20 build 74, can't see anything problematic in it, and it runs OK. I'm using Windows 10 for the test. For info, what operating system are you using?

Regards,
Duncan

Duncan, thanks for the quick reply. Currently using Win 7 here. Did some testing and its four models out of the list that produce the error.?

Very strange.

In PSUD 2.1 build 63 on Windows 7, Adam's oops.psu file throws an error on loading. Help does nothing. OK shows numbers, all 10000M.

The circuit looked OK but I never saw the SiC rectifier. On a hunch I changed to generic Bridge-1000. This runs fine as expected.

I think the problem might be in the rectifier file. I've noticed it has a very high VLaw value (81) which doesn't look right and may encourage numeric overflows.

It was always the case historically that people could upload their own rectifier models to the website, however this has led to some models with bizarre values in that can throw an exception. I've stopped that a couple of years ago and removed 31 rectifier models which had values in that clearly could not work. Some (like this one) were borderline so I left them in.

Ongoing, on PSUD3, the only rectifier models that will get issued with the software are ones that I will have hand-checked against data sheets and signed off. This won't stop people adding or reusing their own models in the privacy of their own homes, it will just stop untested models getting into the core distribution and give those who don't dabble in the models to have a safe and consistent platform to work from.

Hope this explains what might be going on here and what is being done to sort it out.
