4. Granular tensegrity approach
However, the approach described above needs to be supplemented by information derived from experimental observations, to guide the evolution of models towards realistic cytoskeletal architectures. It has therefore led to the development of another, more original model, which overcomes the problems linked to the specificity of each cell and, to go even further, takes into account dynamic processes such as the polymerization/depolymerization of cytoskeleton filaments, as well as their variable connectivity over time.
To this end, a coupling between cellular tensegrity approaches and theoretical and numerical tools specific to discrete media mechanics has been proposed, the latter enabling dynamic interaction processes to be modeled. The idea is to determine a model for which the geometry of the structure is not chosen a priori, but is derived from a simulation of...

LMGC90 software is a development platform dedicated to modeling interaction problems, such as granular materials and block buildings. Bodies can be rigid or deformable (discrete elements, finite elements with multi-physics coupling) and interactions can be of any nature (contact, friction, cohesion, etc.). It consists of a library of components (modules) that can be used via a macro language, relying as far as possible...
