RFI Optimizer has two functions. One is that the RFI will be changed as a new RFI file format. The other is a size reduction.
If the user wants to use the latest formatted RFI file, the best way is to generate a new RFI file using the RFlex interface in the latest version of RecurDyn. The other way is using RFI Optimizer. If the user doesn’t have the input files for RFlex interface and only has the RFI file made by the previous version of RecurDyn, the user can only use RFI Optimizer.
