A Note on System and Hardware Requirements

For hardware requirements (RAM, CPU, Video card), refer to the Readme.PDF file included in the installation folder of your respective Bentley product. In general, hardware requirements are highly dependent on the size and complexity of the model. The more elements and more complexity in the model and the longer the simulation duration, the more memory it will take up and the more a faster CPU will impact overall performance.
