Hi, Vaclav,

not sure, it is a right place for such question, but will try.

I have in RpmMat variable, called "exampleNumber", which indicates the
number of
the specimen. In one simulation I have several of them.

How can you recommend me to "divide" specimens with this parameter?
I need to create several materials with the same parameters, but with
different "exampleNumber"?
Or you can suggest a better solution?

Thank you
