Hello every one. I am working with this simulation software an d I wonder how can I introduce the correlation in my simulation ?

when you specify your assumptions (you assign a probability distribution to a variable) there is a button 'correlation' there (or correl), there you can specify correlation, or let crystal ball calculate it.

Alternatively, there is a menu item called correlation matrix tool, (on the right-most menu title) that lets you specify a region on your spreadsheet for the correlation matrix.

another question: when I let Excel calculate the correlations with the Data analysis toolpack, it gives other correlations then when I calculate them with Crystal Ball.Can anyone explain these differences?

How are you calculating them with Crystal Ball? I've never calculated correlations using Crystal Ball.
