Geomiso ISA: a hybrid software for isogeometric analysis with plate elements and advanced spline techniques

Summary

In this paper, we propose the Geomiso ISA program (www.geomiso.com), a new hybrid software for applications on static isogeometric analysis with plate elements. It is based on the isogeometric analysis, the powerful generalization of the traditional finite element analysis, which, in combination with the plate theory, has attracted increasing attention in construction industry over the last decade, as it achieves efficient design-throughanalysis procedures and shows superior performance. This recently developed program is not just a plug-in, but a both on-premises and cloud-based software solution, applicable to thin (Kirchhoff-Love theory) and thick (Mindlin-Reissner theory) plates. It is used to simulate spline models of slabs and analyze their strength and behavior, while it has many features in common with both finite element software and design programs. This new software solution addresses the rising industrial need for seamless integration of computer-aided design and computer-aided analysis, while it appears to be more efficient to finite element software packages with major improvements, as it facilitates the geometry modeling within analysis, and achieves superior accuracy per degree-of-freedom with shortened computational cost. This is the first time ever such a both on-premises and cloud-based software package has been developed.
