running the model: no convergence   Message List  
Reply | Forward Message #68 of 183 |
Hello,

first I have to say, that this group ist very usefull! Thanks!

Here my question:
I have problems with convergence by running the modell. Sometimes you
can see in the residualgraph (running modus) a up and down in a very
regular way. This leads to "no convergence", if the maximun of
iteration ist reached.
Do you have any idea, whats wrong with the model, if doing in this way
by running the model?

Thanks for helping!
