Static or Dynamic Reduction (Nastran), weird question?

[ultu]

Hello everyone,

I am absolut newbie nastran and reduction methods.

I am reading the nastran superelements user's guide.

It describes a reduction like this:

You have a model.
You split it in two parts.
You reduce one part.
and insert it into the not reduced part
and calculate.

My Question is:
You have a model with million nodes.
You reduce this model using the reduction methods(guyan/fixed or free)
and do your ccalculation.

But there is no single example of this.

Is this procedure possible?
IF yes, are there any examples?

Thank you
Kahn
