Multibody Dynamics for Creo

The Creo - RecurDyn Interface (CRIX) brings Multibody Dynamics to Creo users by simplifying the workflow of getting data from Creo over to RecurDyn. With this new Multibody Dynamics for Creo tool you can export an assembly from PTC Creo and the summary of geometry, as well as all the joints associated with the geometry, into RecurDyn. In the past the workflow of getting CAD data into RecurDyn could be a little bit tedious; from identifying parts that have changed to exporting and importing the geometry, then recreating joints and contacts; there were many opportunities to make a mistake. CRIX does the tedious parts for you so you can focus on modeling and simulation. Key advantages to this new interface include:

  • Easier to start modelling - transfer joints created in Creo directly into RecurDyn
  • Preserves your assembly structure
  • Avoid duplicating work – if joints are available in CAD they shouldn’t need to be recreated in your MBD model
  • Keep geometry up to date – no need to remember or find your (or other's) geometry changes
  • Much simpler than Creo Importer – Reduce clicks by 90% -- 6 clicks instead of ~60

Now with Multibody Dynamics for Creo, if you already have a dynamic model built in Creo you don’t have to recreate everything inside of RecurDyn since Creo Mechanism joints can be automatically converted to RecurDyn joints. With the new interface you can export your assembly and some of the metadata into RecurDyn and easily keep it up to date.

The workflow with the new Multibody Dynamics for Creo interface allows the import process to be completed in record time. Based on your simulation, you may make some CAD changes and you need to export those changes and bring them back into RecurDyn. And then there might also be changes that have been made by somebody else in the organization, which you may or may not know about. Multibody Dynamics for Creo handles the export and updates any existing RecurDyn components while making sure that any joints and contacts already created are preserved.

Inside of RecurDyn you have the option to modify the assembly structure. By default, the assembly structure is preserved, mapping subassemblies into subsystems recursively. This can be easily modified to merge subassemblies into a single body for simpler MBD modeling while retaining the ability to update each part individually.

Another feature is that that each of these pieces operates independently, so the person exporting the Creo assembly doesn't need to have RecurDyn installed and the RecurDyn user doesn't need to have Creo installed. The Multibody Dynamics for Creo tool creates a portable .crix file that contains all the necessary information, both geometry and metadata, and that can be shared to anyone involved in the process.
