In one of your answers you provided the source, from there i got the matlab file. i was thinking of doing a project on it, but i cant run the file. its showing error.

i provided the value of ftBC = 1. I have no priorknowledge of matlab. i want to learn it though.

You editted the code for top99neo.m which you should not have done. You need to restore the code to the original -- in particular you need to restore the first line of code to be

function top99neo(nelx,nely,volfrac,penal,rmin,ft,ftBC,eta,beta,move,maxit)

After that, at the MATLAB command line give the command

 top99neo(120, 40, 0.5, 3, 1.5, 1, 1, 0.5, 2, 0.2, 500)
