Force tuning has recently proven its efficiency with a maximum error of 5% in comparison with standard 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 softwares used for finite element analysis comparison
* Non-linear materials
* Steady state convergence for LBMS
