Enhanced Floating Isogeometric Analysis
Computer Methods in Applied Mechanics and Engineering, 2023 The numerical simulation of additive manufacturing techniques promises the acceleration of costly experimental procedures to identify suitable process parameters. We recently proposed Floating Isogeometric Analysis (FLIGA), a new computational solid mechanics approach, which is mesh distortion-free in one characteristic spatial direction.

SoftIGA: Soft isogeometric analysis
Computer Methods in Applied Mechanics and Engineering, 2023 We extend the softFEM idea to isogeometric analysis (IGA) to reduce the stiffness (consequently, the condition numbers) of the IGA discretized problem. We refer to the resulting approximation technique as softIGA. We obtain the resulting discretization by first removing the IGA spectral outliers to reduce the system's stiffness.

Igatools: An Isogeometric Analysis Library [PDF]
SIAM Journal on Scientific Computing, 2015 Summary: We present the design of an object oriented general purpose library for isogeometric analysis, where the mathematical concepts of the isogeometric method and their relationships are directly mapped into classes and their interactions. The encapsulation of mathematical concepts into interacting building blocks gives flexibility to use the ...
