Hi,
Thanks for your reply. In my model, the error appears when I set lower limits for some of dependent variables in segregated study. One of modules is the transport of concentrated species which has three components. But actually two mass fractions are solved and the other one is calculated by 1-w1-w2, whose lower limit cannot be set. So when I move the mass faction w3, the third component out the setting colume, the error disappears. So I guess maybe the problem comes up from some variable cannot being set limit. Do you have any such variables in your model?
Hope this can help you!
Good luck!
