                        - Altair Community: Click the
                                Documentation link, choose filter options,
                            and select Model as the Output Type. 
 
                        - Altair Marketplace: Search for and select
                            the product you want, click the Download tab, and
                            in the Select Type list, select the applicable
                            model file option.
 
                    
                 
                
                    Tip: You must unzip the model files before
                        proceeding with the tutorials and verification problems. When extracting
                        zipped files, preserve any directory structure included in the file
                        package.
