我建的是巷道模型，模型包括，矿体上下盘，巷道，支护圈，共九个group，我想给其中3个定义一样的材料，可是无法完成！
程序如下
model mohr
prop bulk=6.04e8 shear=3.45e8 fric=28.9 coh=6.1e5 tension=1.05e6 range group 3 and group 7 and groep 4
prop bulk=1.3747e10 shear=9.053e10 fric=30.8 coh=9.27e6 tension2.07e6 range group 2 and group 8 and group 5
prop bulk=1.0567e10 shear=6.34e8 fric=28.7 coh=9.27e6 tension=3.05e6 range group 1 and group 9 and group 6
