Recurring Meeting of Cleveland Clinic - University of Utah

Date: February 8, 2017

Time: 2:00 PM EST

Means: Conference call


  1. Ahmet Erdemir (Cleveland Clinic)
  2. Jeff Weiss (University of Utah)
  3. Steve Maas (University of Utah)
  4. Ben Ellis (University of Utah)


  1. Ongoing and planned activities at Cleveland Clinic.
  2. Ongoing and planned activities at University of Utah.
  3. Other.

Immediate Action Items:


  1. Ongoing and planned activities at Cleveland Clinic.
    • Ahmet mentioned that Ben, who is an engineer working with him, successfully used in situ strain feature for gravity compensation. Ben had found some discrepancies in documentation of the plug-in. Steve recommended that Ben contact him in this regard.
    • Ahmet reminded the University of Utah group about possible no cost extension to continue the project. Jeff will check with his administrative team to see where University of Utah stands. In response to Jeff, Ahmet summarized his plans for prospective grant submissions.
  2. Ongoing and planned activities at University of Utah.
    • Jeff noted Gerard's work on shell elements to accommodate multiphasic materials. The implementation was motivated by simulations of transport to cells. He also noted the new shell elements that are higher order and in result have better performance and stability.
    • Steve has not done additional work on wrapping springs. He may explore simplification of beam problems to resolve stability issues.
    • In regard to shell and membrane element implementations and spring formulations, Jeff advised Steve to interact with the computational mechanics community in more depth. This can help to familiarize with the latest developments in the area. Ahmet will be happy to provide guidance on driving problems.
    • Steve mentioned that the new PreView supports import/export of parts. For modeling, part orientation can be prescribed by a quaternion or using Euler angles. He will update documentation of the part feature to assist Cleveland Clinic's scripting efforts.

  3. Other.
    • The group discussed the possibility for membrane elements in FEBio as these types of elements are likely to be useful for many biomechanical simulations including those of skin and cells. Jeff noted that it may be possible to have membrane elements by using shell elements with one integration point through the thickness. Stability was raised as a concern.
    • Ahmet asked the possibility for scripting support in FEBio, particularly using Python. The University of Utah team has an interest to facilitate this.
