  3. 18. The fW-mean filter framework for topology optimization and analysis of Friedrichs systems

    Författare :Linus Hägg; Martin Berggren; Eddie Wadbro; Björn Engquist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; topology optimization; filters; mathematical morphology; size control; minimum compliance problem; Friedrichs systems; well-posedness; variational formulations; linearized Euler’s equations; Galbrun’s equation; acoustics; Mathematics; matematik;

    Sammanfattning : Part I. Topology optimization is the most general form of design optimization in which the optimal layout of material within a given region of space is to be determined. Filters are essential components of many successful density based topology optimization approaches. LÄS MER
