There are two parts to exporting Fill+Pack, Fiber and Warp results for 3D models to Abaqus: the first is running the mpi2abq.vbs macro to create the necessary files; the second is locating the files and using them in Abaqus.
To run the mpi2abq.vbs macro from the user interface:
The API script saves the interface files in a folder created within the current project folder. For example, My Documents\My AMI 20xx Projects\Project1\<study_name>_interface_files, where xxxx is the software release number and <study_name> is the name of the study you are exporting to Abaqus).
Once the files are in that location, you can use them in Abaqus. Refer to your Abaqus manual for instructions on how to import them.
