第1部分命令流按照顺序进行
2-1定义一个FISH函数
new
def abc
abc = 25 * 3 + 5
End
print abc
2-2使用一个变量
new
def abc
hh = 25
abc = hh * 3 + 5
End
Print hh
Print abc
2-3对变量和函数的理解
new
def abc
hh = 25
abc = hh * 3 + 5
End
set abc=0 hh=0
print hh
print abc
print hh
new
def abc
abc = hh * 3 + 5
end
set hh=25
print abc
set abc=0 hh=0
print hh
print abc
print hh
2-4获取变量的历史记录
new
gen zone brick size 1 2 1
model mohr
prop shear=1e8 bulk=2e8 cohes=1e5 tens=1e10
fix x y z range y
apply yvel -1e-5 range y
plot set rotation 0 0 45
plot block group
def get_ad
ad1 = gp_near(0,2,0)
ad2 = gp_near(1,2,0)
ad3 = gp_near(0,2,1)
ad4 = gp_near(1,2,1)
end
get_ad
def load
load=gp_yfunbal(ad1)+gp_yfunbal(ad2)+gp_yfunbal(ad3)+gp_yfunbal(ad4) end
hist load
hist gp ydis 0,2,0
step 1000
plot his 1 vs -2
2-5用FISH函数计算体积模量和剪砌模量
new
def derive
s_mod = y_mod / * + p_ratio))
b_mod = y_mod / * - * p_ratio))
end
set y_mod = 5e8 p_ratio =
derive
print b_mod
print s_mod
2-6 在FLAC输入中使用符号变量
New
def derive
s_mod = y_mod / * + p_ratio))
b_mod = y_mod / * - * p_ratio))
end
set y_mod = 5e8 p_ratio =
derive
gen zone brick size 2,2,2
model elastic
prop bulk=b_mod shear=s_mod
print zone prop bulk
print zone prop shear
2-7 控制循环
New
def xxx
sum = 0
prod = 1
loop n (1,10)
sum = sum + n
prod = prod * n
end_loop
end
xxx
print sum, prod
new
gen zone brick p0 (0,0,0) p1 (-10,0,0) p2 (0,10,0) p3 (0,0,-10) model elas
plot set rotation 0 0 45
plot block group
def install
pnt = zone_head
loop while pnt #null
z_depth = -z_zcen(pnt)
y_mod = y_zero + cc * sqrt(z_depth)
z_prop(pnt, ’shear’) = y_mod / *+p_ratio))
z_prop(pnt, ’bulk’) = y_mod / *
pnt = zone_next(pnt)
end_loop
end
set p_ratio= y_zero=1e7 cc=1e8
install
2-8 拆分命令行
new ;example of a sum of many things
def long_sum
temp = v1 + v2 + v3 + v4 + v5 + v6 + v7 + v8 + v9 + v10 long_sum = temp + v11 + v12 + v13 + v14 + v15
end
2-9 变量类型
new
def haveone
aa = 2
bb =
cc = ’Have a nice day’
dd = aa * bb
ee = cc + ’, old chap’
end
haveone
print fish
2-10 IF条件语句
new
def abc
if xx > 0 then
abc = 1000
else
abc = -1000
end_if
end
set xx = 10
print abc
set xx = 0
print abc
2-11 索单元自动生成
new
gen zone brick size 10 3 5
plot set rotation 0 0 45
plot block group
def place_cables
loop n (1,5)
z_d = float(n) -
command
sel cable beg ,,z_d end ,,z_d nseg 7 end_command
end_loop
end
place_cables
plot grid sel geom red
new
