How To Use the Ungroup Models Operator

M_Martin

Hi Colleagues:  Can anyone point me in the right direction as to how to use the Ungroup Models Operator?  OI am feeding a grouped model into this operator, and a see that a collection of models is coming out of it, but I can't find any documentation that would tell me how to grab the single model within the grouped model that I would like to use further on in my process.  Thanks for any guidance!  Best wishes, Michael Martin

Hi @M_Martin,

after ungroup, you get a collection of models/objects. You can use “Select” operator by specifying an index to extract individual model from the collections.

Hi yyhuang:  Thanks very much for your reply - very much appreciated - which seems to solve the problem.  Where I went wrong is that I put the Select Operator inside of a Loop Collection operator and when the iteration started, I got an error message stating that the operator expected a model but was receiving an IOObject Collection.  Not using the Loop Collection operator looks to have solved my problem.  Best wishes!  Michael Martin
