Hi everyone, I want to scan over a set of parameters. Currently however, I always get the error: "Attempt to reference field of non-structure array" after the simulation is run exactly once. I tried whether it was a problem with that specific parameter - it isn't. Also turning off parts of the simulation doesn't help.

I don't know how to approach this problem since this has worked before and I didn't fundamentally change my model.

Any ideas? Any help would be greatly appreciated.

Thanks, Michael

@Arthur Goldspie: I only have that particular project I am working on at the moment that has this problem. Here is a link to download it, feel free to check it out. click

Thank you!

This is difficult to answer without additional information. Can you attach a project that reproduces the problem? Can you also tell us what version of SimBiology you're using and what platform? (Windows?)

Hi Michael,

The error happens because there is a clash between the parameter named "count" in your model and an internal variable named count. You can work around this by renaming the parameter to something other than "count" e.g: counter.

We are planning on fixing this in a future release.
