   Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER

3. 2. Finite Element simulations: computations and applications to aerodynamics and biomedicine

   Författare :Massimiliano Leoni; Johan Hoffman; David Kamensky; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiofrequency ablation; finite elements; numerical simulations; partial differential equations; biomedical applications; HPC; Computer Science; Datalogi;

   Sammanfattning :   Partial Differential Equations describe a large number of phenomena of practical interest and their solution usually requires running huge simulations on supercomputing clusters.  Especially when dealing with turbulent flows, the cost of such simulations, if approached naively, makes them unfeasible, requiring modelling intervention.
