Hello,<BR>
<BR>
I have some difficulties to mesh in 3D my model the way I want.<BR>
Here is my .geo:<BR>
<BR>
Point(1) = {175, 0, -160};<BR>Point(2) = {-175, 0, -160};<BR>Point(3) = {-175, 0, 160};<BR>Point(4) = {175, 0, 160};<BR>Point(5) = {-50, 0, -50};<BR>Point(6) = {-50, 0, 50};<BR>Point(7) = {50, 0, -50};<BR>Point(8) = {50, 0, 50};<BR>Point(9) = {175, -250, -160};<BR>Point(10) = {-175, -250, -160};<BR>Point(11) = {-175, -250, 160};<BR>Point(12) = {175, -250, 160};<BR>Point(13) = {175, -130, 50};<BR>Point(14) = {175, -30, 50};<BR>Point(15) = {175, -130, 150};<BR>Point(16) = {175, -30, 150};<BR>Point(17) = {-100, -250, -120};<BR>Point(18) = {-100, -250, -140};<BR>Point(19) = {100, -250, -140};<BR>Point(20) = {100, -250, -120};<BR>Point(21) = {-100, -400, -140};<BR>Point(22) = {-100, -400, -120};<BR>Point(23) = {100, -400, -120};<BR>Point(24) = {100, -400, -140};<BR>Point(25) = {375, -30, 50};<BR>Point(26) = {375, -130, 50};<BR>Point(27) = {375, -130, 150};<BR>Point(28) = {375, -30, 150};<BR>Point(29) = {-50, -100, -50};<BR>Point(30) = {-50, -100, 50};<BR>Point(31) = {50, -100, -50};<BR>Point(32) = {50, -100, 50};<BR>Line(1) = {1, 2};<BR>Line(2) = {2, 3};<BR>Line(3) = {3, 4};<BR>Line(4) = {4, 1};<BR>Line(5) = {5, 6};<BR>Line(6) = {7, 5};<BR>Line(7) = {8, 7};<BR>Line(8) = {6, 8};<BR>Line(9) = {1, 9};<BR>Line(10) = {9, 10};<BR>Line(11) = {2, 10};<BR>Line(12) = {10, 11};<BR>Line(13) = {3, 11};<BR>Line(14) = {11, 12};<BR>Line(15) = {4, 12};<BR>Line(16) = {12, 9};<BR>Line(17) = {13, 14};<BR>Line(18) = {15, 13};<BR>Line(19) = {16, 15};<BR>Line(20) = {14, 16};<BR>Line(21) = {17, 18};<BR>Line(22) = {18, 19};<BR>Line(23) = {19, 20};<BR>Line(24) = {20, 17};<BR>Line(25) = {18, 21};<BR>Line(26) = {22, 21};<BR>Line(27) = {17, 22};<BR>Line(28) = {23, 22};<BR>Line(29) = {20, 23};<BR>Line(30) = {24, 23};<BR>Line(31) = {19, 24};<BR>Line(32) = {21, 24};<BR>Line(33) = {14, 25};<BR>Line(34) = {26, 25};<BR>Line(35) = {13, 26};<BR>Line(36) = {27, 26};<BR>Line(37) = {15, 27};<BR>Line(38) = {28, 27};<BR>Line(39) = {16, 28};<BR>Line(40) = {25, 28};<BR>Line(41) = {5, 29};<BR>Line(42) = {29, 30};<BR>Line(43) = {6, 30};<BR>Line(44) = {7, 31};<BR>Line(45) = {31, 29};<BR>Line(46) = {8, 32};<BR>Line(47) = {32, 31};<BR>Line(48) = {30, 32};<BR>Line Loop(1) = {1, 2, 3, 4, 5, 8, 7, 6};<BR>Plane Surface(1) = {1};<BR>Line Loop(2) = {1, 11, -10, -9};<BR>Plane Surface(2) = {2};<BR>Line Loop(3) = {2, 13, -12, -11};<BR>Plane Surface(3) = {3};<BR>Line Loop(4) = {3, 15, -14, -13};<BR>Plane Surface(4) = {4};<BR>Line Loop(5) = {4, 9, -16, -15, 17, 20, 19, 18};<BR>Plane Surface(5) = {5};<BR>Line Loop(6) = {10, 12, 14, 16, 21, 22, 23, 24};<BR>Plane Surface(6) = {6};<BR>Line Loop(7) = {21, 25, -26, -27};<BR>Plane Surface(7) = {7};<BR>Line Loop(8) = {24, 27, -28, -29};<BR>Plane Surface(8) = {8};<BR>Line Loop(9) = {23, 29, -30, -31};<BR>Plane Surface(9) = {9};<BR>Line Loop(10) = {22, 31, -32, -25};<BR>Plane Surface(10) = {10};<BR>Line Loop(11) = {26, 32, 30, 28};<BR>Plane Surface(11) = {11};<BR>Line Loop(12) = {17, 33, -34, -35};<BR>Plane Surface(12) = {12};<BR>Line Loop(13) = {18, 35, -36, -37};<BR>Plane Surface(13) = {13};<BR>Line Loop(14) = {19, 37, -38, -39};<BR>Plane Surface(14) = {14};<BR>Line Loop(15) = {20, 39, -40, -33};<BR>Plane Surface(15) = {15};<BR>Line Loop(16) = {34, 40, 38, 36};<BR>Plane Surface(16) = {16};<BR>Line Loop(17) = {5, 43, -42, -41};<BR>Plane Surface(17) = {17};<BR>Line Loop(18) = {6, 41, -45, -44};<BR>Plane Surface(18) = {18};<BR>Line Loop(19) = {7, 44, -47, -46};<BR>Plane Surface(19) = {19};<BR>Line Loop(20) = {8, 46, -48, -43};<BR>Plane Surface(20) = {20};<BR>Line Loop(21) = {42, 48, 47, 45};<BR>Plane Surface(21) = {21};<BR>Surface Loop(1) = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21};<BR>Volume(1) = {1};<BR>
lc=5;<BR>
<BR>Field[1] = Attractor;<BR>Field[1].EdgesList = {48, 47, 45, 42};<BR>
<BR>Field[2] = MathEval;<BR>Field[2].F = "3";<BR>
<BR>
Field[3] = Restrict;<BR>Field[3].IField = 2;<BR>Field[3].FacesList = {21};<BR>
<BR>
Field[4] = Threshold;<BR>Field[4].IField = 1;<BR>Field[4].LcMin = 3;<BR>Field[4].LcMax = 10;<BR>Field[4].DistMin =0;<BR>Field[4].DistMax = 50;<BR>
<BR>Field[5] = Min;<BR>Field[5].FieldsList = {3, 4};<BR>
Background Field = 5;<BR><BR>
The 2D mesh gives me the result I want: a uniform mesh on the surface 21, and the same size of mesh on the other surfaces.<BR>
But for the 3D mesh, what I want is the result of the threshold field on the surface 21. I know I can't define this surface as an attractor since it doesn't work so well with surfaces. So please, if you have any idea for my problem...<BR>
