patran mpc id conflict

[drpulsae]

Dear users of the forum, I am modeling in patran a welded and bolted structure (elements 2d shell). the bolted links model them using cbar elements that connect the independent nodes of mpc elements. I made a bdf of the model, just to evaluate the number of knots so far produced and I realized that for all mpc created I was reported this string:

"$ id conflict: the patran mpc id was 239
51672 51674 51693 51695
51714 51715 51716"

for completeness I add that when I realized the bdf (analyze entire model analysis deck) I had not yet applied neither property, nor constraints, nor loaded to all elements of the model. I want to know what consequences the id conflict entails, if it is solved, for example by renumbering the mpc and how I can do to prevent future warnings. I trust your contribution.

No problem.
you simply have an element and an mpc with the same id. in patran you can do in nastran no.
so when Patran creates bdf, he renames mpc by giving him another id. in your case the id given in patran was 239 and now renamed it in 95021. He probably put it at the end of all the elements.

You were very kind to answer. I almost finished modeling... I will give the propitiousness, I will apply constraints, loads and launch the analysis as soon as possible, hoping that everything will be okay and that the episilon is acceptable.
