Hi Jaromir,
 
I don't know if you already had of comments concerning this problem. If it's case sorry for the repetition of this informaton. I seem to have a problem with the last updated of Iriss (version 20131126). I have a model for which I combined steady state and dynamic model. When I tried to solve my model with the version (20131111), I didn't find any problems. But with the version (20131126) the model didn't solve and stop and fail at chksstate. Have you an idea where this problem come from? Thanks for your answer and for your great job, this tools is really awesome.

Hi Jose

Could you please attach/upload the model file plus other files so that I can run that piece of code? Thanks,

Jaromir

José

I've gone through all committed changes affecting the steady state solver between the two releases -- there are just two or three minor ones, and there seem to be none that would in ay way could change its behavior. I'd therefore really like to understand what's going on... Could you please post/attach your code or a mat file so that I can run it on my comp? Also, I suppose the versions of Matlab are identical in both cases, aren't they?

Thanks Jaromir,
 
Sorry Jaromir, for my late I was really busy these last times. Yes I used the same versions of Matlab. But I can't send you my model or my mat file because these are of sensible informations.
 
José
