Hey! I’m Hugo Verhelst, a post-doctoral researcher at the Department of Mathematics of the University of Florence (Italy) and remotely at the Department of Maritime and Transport Technology at the Delft University of Technology (The Netherlands).

My current work focusses on the development of structural analysis tools for thin membrane structures at sea, using the mathematical concept of Isogeometric Analysis. In particular, I mainly contribute to the field of computational structural analysis and I am a co-developer of the Geometry+Simulation Modules (G+Smo).

Software

Geometry + Simulation Modules (G+Smo) - Core

G+Smo (pronounced gismo or gizmo) is a C++ library for isogeometric analysis (IGA). Geometry plus simulation modules aims at the seamless integration of Computer-aided Design (CAD) and Finite Element Analysis (FEA).
Developer

Geometry + Simulation Modules (G+Smo) - gsKLShell

gsKLShell is the module in G+Smo implementing the isogeometric Kirchhoff-Love shell formulation. gsKLShell offers geometric and material non-linearities, error estimators using the Dual-Weighted Residual method, and more.
Main developer

Geometry + Simulation Modules (G+Smo) - gsStructuralAnalysis

The gsStructuralAnalysis module provides routines for structural analysis in G+Smo. Besides conventional routines for buckling, post-buckling, static and modal analysis, it provides a parallel arc-length method.
Main developer

Geometry + Simulation Modules (G+Smo) - gsUnstructuredSplines

The gsUnstructuredSplines module provides unstructured spline constructions for isogeometric analysis in G+Smo, enabling multi-patch isogeometric analysis.
