I'm interested to know how long it takes for your computer to run the attached model in both Simulation Professional and Express.
Model was created in SolidWorks 2010 SP4.
To find run time in Professional, after running the study, RMB click on results and select solver messages.
I found it the study would run much quicker in Express than Professional with the same mesh size.
Does Express use a draft mesh?
