Consulting for the Medical Industry

NEi Software's consulting team offers expertise in the FEA simulation of intraocular lenses (IOL) and their implantation, through working with a wide range of industrial and research organizations.

A lens analysis typically requires special attention paid to the solid modeling used to create the part with its subtle shapes. NEi Software is highly experienced in working with clients to repair geometry or to produce the CAD data with the objective of ensuring that a high quality finite element mesh is produced. The lens is usually highly flexible and will be pushed or supported by surrounding media. It is important to include geometric nonlinearity and 3D contact in this type of problem. NEi Nastran performs exceptionally well in simulating the "snap through" effect shown by many flexible lenses.

NEi Software is also working with manufacturers to study the movement and mechanical performance of a variety of orthopedic implant devices, including spinal screws and stabilizing structure. Again the emphasis is on highly detailed, accurate 3D models. Full support is given for importing stereo images to provide the basis of the 3D model. The models have the full range of nonlinearity for large deformation, pre-load, 3D contact and plastic material behavior. In addition general 3D anisotropy can be used to model bone like structures.
