QUAD-SURFACE 2.8

Quality finite element meshing for analysis of plates and shells -

with source codes available !

QUAD-SURFACE highlights.

Thin plates and shells comprise bodies of various structures commonly encountered in modern industries, particularly in the automotive and aeronautical. Analysis - with high degree of precision - of stresses, natural frequencies and other mechanical properties of such structures is absolutely vital; this is because if numerical results are “too approximate” then the structure will be either too heavy (if the actual stresses are lower than calculated ones), or not possessing required strength (in the opposite case).

It is well-known fact that quadrilateral finite elements deliver very accurate numerical results; for that reason, generators producing 100% quadrilateral meshes are highly desirable in FEA systems. That is what QUAD-SURFACE was developed for; it is the newest addition to the full range of our state-of-the- art quadrilateral mesh generation products.

QUAD-SURFACE allows:

• meshing of complex plate and shell structures in 3D space, consisting of flat, cylindrical, spherical components, surfaces of revolution and also general-case 3- and 4-edged patches;
• meshing of non-homogeneous domains, consisting of multiple plates and shells with different physical and/or geometrical properties;
• easily readable and convenient description of geometrical models;
• fully automatic processing, requiring no interference from the user;
• automatic processing of internal and boundary constraints - new feature for QUAD-SURFACE 2.8 !

Licensing, delivery and support.

QUAD-SURFACE is available in the complete source code form, with full commercial license allowing incorporation into your own products. QUAD-SURFACE is written in ANSI C : it will compile and run on any Windows and UNIX platform, without changes to the source code. It is available on no-royalties and no annual renewals basis: there is a one-off price for the unlimited commercial license.
