The '''Lattice Boltzmann methods for solids (LBMS)''' are a set of methods for solving [[Partialpartial differential equation|partial differential equations]]s (PDE) in solid mechanics. The methods use a discretization of the [[Boltzmann equation]](BM), and their use is known as the lattice Boltzmann methods for solids.

LBMS methods are categorized by their reliance on:

Force tuning<ref name="mnnclbms"/> has recently proven its efficiency with a maximum error of 5% in comparison with standard [[Finite element method|finite element]] solvers in mechanics. Accurate validation of results can also be a tedious task since these methods are very different, common issues are:

* Meshes or lattice discretization

* Location of computed fields at elements or nodes

* Hidden information in softwaressoftware used for [[Finite element method|finite element analysis]] comparison

* Non-linear materials

* Steady state convergence for LBMS
