flags(i,j)是什么意思,请教高手
def relax_ininstart = step;步数
nstop = nstart + ninc;步数+1000
end
def relax_hist
if step < nstop;当前步数小于停止步数时
step_inc = float(step - nstart);当前-开始
relax_hist = rstart - ((rstart - rstop)/ float(ninc)) * step_inc;
else
relax_hist = rstop
endif
end
def apply_rf
loop ii (ib_ap,ie_ap);10,17
loop jj (jb_ap,je_ap);34,52
if and(flags(ii,jj), 2) = 2 then
if and(flags(ii,jj), 4) = 4 then
xftmp = -xforce(ii,jj)
yftmp = -yforce(ii,jj)
command
apply xforce=xftmp hist relax_hist i=ii j=jj
apply yforce=yftmp hist relax_hist i=ii j=jj
end_command
endif
endif
endloop
endloop
end
def relax_tractions
relax_ini
relax_hist
apply_rf
end 个人觉得应该是判断该单元是否为null单元!当为null单元，则其值为0
