questions about abaqus software package

Hello

I was analyzing pavement subjected to traffic wheel load. I was using the load as cyclic pressure. Suppose an amount of pressure with 200 different time frame. But I am not getting the right result as measured. So, would you please help on applying moving load? How can I assigned that load as moving load? where can I find the step load function? how can I determine the initial increment? is it more realistic to simulate the wheel load as dynamic? how can I do that?

Thanks a lot.

Best regards,

Loay
