This type is very useful about the RFI file consisted of the Parabolic Tetra Element such as CTETRA (called Solid10) because the RFI file size of this element type is large. In this case, there is no way to reduce the RFI file in NX/NASTRAN. In addition, because the RFI file generated from NX/ NASTRAN has no bulk data information such as Element, Property and Material, RFI Optimizer supports to add them. Finally, if the user reduces the size of RFI file by using this function, the user will see the animation speed as well as the solving speed improved.
Figure 1 RFI Optimizer dialog box [NX Nastran]
•Type: NX Nastran type.
•RecurDyn/RFlex supports from NX Nastran 7.1
•Source RFI File: Selects the RFI file for size reduction. The new RFI file generated from RFI optimizer must not be used again in this function.
•OP2 File: Selects the OP2 file as the FE result generated from NX Nastran when making the RFI file. The OP2 file is used as the input file to add the element information to the RFI file. For more information, refer to How to make the OP2 file.
•Target RFI File: Defines a name of the target RFI file.
•Adding Element/Property/Material Information: Because the RFI file generated from NX Nastran has no information of element, property, and material, the RFI file needs to add this information for optimizer.
•Size Reduction
•Remove Mid-Node Related Information: Removes the mid node related information in the RFI file. For more information, click here.
•Remove Zero-Value for Rotational Mode Shape: Removes the zero value for Rotational Mode Shape in the RFI file just about only solid elements. For more information. click here.
•Change All Patch Info to External Patch Info: Changes all patch information to the external patch information in the RFI file.
