FEA and CFD case studies
Patient-specific Chemotherapeutic Drug Delivery to Brain Tumors
This study illustrates that, with the help of Mimics, an engineer can provide a recommendation to the neurosurgeon to help plan the treatment for a patient-specific brain tumor.
Non-Linear Finite Element Modelling of Anatomically Detailed 3D Foot Model
Linear and non-linear elastic constitutive material models were implemented to mechanically characterize the behaviour of the biological materials. Furthermore, preliminary numerical results for the model's qualitative evaluation are presented.
Morphological study of the proximal femur: a new method of geometrical assessment using 3-dimensional reverse engineering
This study presents a new method of using computerized tomography images combined with reverse engineering technique to obtain and analyze the three-dimensional inner and outer geometry of the proximal cadaveric femur. Three-dimensional models were reconstructed from the computerized tomography images and approximated with 2D and 3D fitting algorithms based on reverse engineering methods.
Mimics Assists in Investigating Impact of Aortic Valve Proestheses on Blood Flow
Alarmed by the high number of people dying from cardiovascular diseases, this research team turned to Mimics and 3-matic to create a simulation model for investigating the impact of aortic valve prostheses on blood flow.
Finite element study of trochanteric gamma nail for trochanteric fracture
A three-dimensional finite element study of trochanteric fracture fixation by a trochanteric gamma nail (TGN, Stryker-Howmedica-Osteonics) was investigated. A TGN is used for fracture fixation in Trochanteric and Subtrochanteric fractures.
Mimics Assists in Understanding Cement – Bone Interface Micromechanics
The researchers in this case were seeking a closer look at the micromechanical behavior in the human femur mantle of bone cement, the adhesive used by orthopaedic surgeons in joint replacement surgery. Their question was whether an FE analysis would yield the same information on the interface’s properties as previously discovered by conducting direct experiments. They turned to Mimics as the perfect partner for the preparation of scanner data for FEA.
Cornell University swaps horses
Imagine the ability to prepare scanned human or animal geometry for CFD analysis in a few days. Cornell University,Ithaca, NY, discovered that, using Materialise’ Remesh technology, they can reduce file preparation time from several weeks to a day or two! The days of moving and reshaping triangle after triangle manually in pre-processing software are gone forever. Remesh technology enables the user to generate a surface mesh quickly. The resulting mesh is directly transformable in a volume mesh for CFD.
Performing accurate, patient-specific biomedical analysis
Together, Mimics and ABAQUS software provide a solution for the successful analysis of complex anatomical geometries. Here we describe some test cases that were presented at the ABAQUS CENTRAL user group meeting. They illustrate how easily you can perform accurate, patient-specific biomedical analysis to support product development.
