Assessment of implicit adaptive mesh‐free CFD modelling
International Journal for Numerical Methods in Fluids, Volume 96, Issue 5, Page 670-700, May 2024.The paper shows results from an implicit meshless method suitable for the analysis of external aerodynamic flows. This research is using a cloud of points instead of cells, and several stencils are compared for the discretization of the flow equations, along with a least‐squares method.

The MLPG for Bending of Electroelastic Plates
Computer Modeling in Engineering & Sciences, 2010 The plate equations are obtained by means of an appropriate expansion of the mechanical displacement and electric potential in powers of the thickness coordinate in the variational equation of electroelasticity and integration through the thickness. The appropriate assumptions are made to derive the uncoupled equations for the extensional and flexural ...
