This study deals with a ubiquitous learning support system for isogeometric analysis (IGA), a kind of the finite element method with NURBS basis functions. Isogeometric analysis does not need any mesh generation process, which is the most time- consuming process in practical finite element analyses, but directly uses geometry data generated in the CAD system, where geometries of objects are defined with the NURBS basis functions. As NURBS basis functions are much more complicated than those of conventional FEM, it is difficult for users/learners to get clear understanding of them and the IGA. The proposed system consists of three sub-systems: a graph display system for NURBS basis functions, a parallel isogeometric analysis system and a 3D visualization system for IGA. All of the systems are designed and implemented to mobile devices based on the Android OS, which realizes the ubiquitousness of the proposed system.
