Abaqus Simulation Run Time

Hey all,

I am running a wave propagation simulation on Abaqus that requires a large number of element and a very small time step(increment). I am using the Dynamic Implicit analysis type. When I run the simulation ,it take a very long time. I even tried using a faster computer(32 GB of RAM) but that did not reduce the time by much! Is there anything I can do to reduce the time it take that simulation to complete? 

Also, the .odb file is very big(about 1 GB) although I only have requested one Field Output(displacement) and one History Output(also displacement). Any idea if that is normal ? 

Thank you for your help!

Regards.
