A framework for Soft-tissue Deformation
2009 (English)In: Proceedings of SIGRAD Conference 2009, 2009, 27-29 p.Conference paper (Other academic)
For the simulation of soft tissue deformation Finite ElementMethod (FEM) has been the technique which achieves most physicallyrealistic behaviour. However to provide stable force feedback,high refresh rates are needed which makes the use of FEMnon-trivial.To solve the challenge of the compromise between speed and realism,asynchronous regions which solves different parts of the modelwith different frequencies and different resolutions are used. Thelocal neighbourhood of the contact is solved with higher frequencyand resolution while the more remote regions are solved with lowerfrequency and resolutions. Different solution methods, implicit andexplicit, can be used to solve different regions and the size of theregions can be adapted depending on the strain to maximize theefficiency.
