QUAD-SURFACE 2.8

available with complete source codes.

QUAD-SURFACE: generator of QUAD8 and QUAD9 elements on curved surfaces in 3D space.

Significant number of constructions in the modern structural engineering  are complex spacial combinations of plates and shells. In many cases, they are made of composite materials, often consisting of several anisotropic layers. Whereas 4-noded bilinear finite elements often deliver acceptable results in terms of nodal displacements, the situation with components of the stress tensor can be very different: in order to achieve required numerical accuracy, 8-noded Serendipity and/or 9-noded Lagrangian elements must often be used.

QUAD-SURFACE is mesh generator capable of delivering exceptionally accurate finite element meshes for a broad range of surfaces in 3D such as: plane, cylindrical, spherical, general 3D and their arbitrarily complex spacial combinations. Most importantly, the additional nodes of QUAD8 and QUAD9 elements are always placed on the surface too, thus preserving as much as possible the original shape of the surface. As our experience demonstrated, the surface shape preservation is absolutely necessary for obtaining accurate resutls in terms of the stress tensor components.

QUAD-SURFACE (as well as all of our world-class quadrilateral mesh generators) is available in the complete source code form, on no-royalties and no-annual- renewals basis: there is a one-off price for the unlimited commercial license.
