Generate the Grid of FLAC3D (Units Join)

Should confirm continuity of the interface before join basic units together.

Apply  GENERATE point  checking the bound of  interface whether  acceptable  is very useful.  Sometimes we can also apply PLOT sketch and PLOT boundary command checking units manually , GENERATE merge is often applied after find mismatch express local rate abnormal .

Example 1: join two different units.

gen zone brick size 4 4 4 p0 0,0,0 p1 4,0,0 p2 0,4,0 p3 0,0,2
gen zone brick size 8,8,4 p0 0,0,2 p1 4,0,2 p2 0,4,2 p3 0,0,4
attach face range z 1.9 2.1
model elas
prop bulk 8e9 shear 5e9
fix z range z  -.1 .1
fix z range x  -.1 .1
fix x range x  3.9 4.1
fix y range y  -.1 .1
fix y range y 3.9 4.1
apply szz -1e6 range z 3.9 4.1 x 0,2 y 0,2
hist unbal 
solve

Example 1: simple unit.

gen zone brick size 8 8 8 p0 0,0,0 p1 4,0,0 p2 0,4,0 p3 0,0,4
model elas
prop bulk 8e9 shear 5e9
fix z range z  -.1 .1
fix z range x  -.1 .1
fix x range x  3.9 4.1
fix y range y  -.1 .1
fix y range y 3.9 4.1
apply szz -1e6 range z 3.9 4.1 x 0,2 y 0,2
hist unbal 
solve
save noatt.sav

  • Dear Sir,
    I don't understand what the negative sign and positive sign of displacement results in Flac3D are. What does those means? If you have a time, could u explain me please.Thank you very much for sharing your knowledge.
