For technical details about the approach, please refer to the paper ``Topology Optimization in B-spline Space'' by Xiaoping Qian in journal Computer Methods in Applied Mechanics and Engineering.

 

Usage: btop85(nelx,nely,volfrac,penal,n_mu, n_mv, mp, mq)

o   nelx, nely: number of analysis elements in x and y directions

o   volfrac: volume fraction

o   penal: penalty

o   n_mu, n_mv: number of knot intervals in x and y directions

o   mp, mq: degrees of uniform B-splines in x and y directions

 

An example from running ``btop85(30,10,0.5,3,30,10,2,2)'' is shown in Fig. 1 which includes the following command line output.
