 December 10, 2010, 04:56 Where are my Cells ?! #1 New Member   Join Date: Dec 2010 Posts: 1 Rep Power: 0 Hay all, im trying to generate a simple cone-cyl simulation. here is my geo file: __________________________________________________ ___________ l1 = 0.05; l2 = 0.01; n=10; Point(1) = {-0, -0, 0,l1}; Point(2) = {0.4, -0, 0,l2}; Point(3) = {0.6, 0.1, 0,l2}; Point(4) = {1, 0.1, 0,l2}; Point(5) = {1, 0, 0,l2}; Point(6) = {1.3, -0, 0,l1}; Point(7) = {1.3, 0.4, 0,l1}; Point(8) = {0, 0.4, 0,l1}; Line(1) = {1, 2}; Line(2) = {2, 3}; Line(3) = {3, 4}; Line(4) = {4, 5}; Line(5) = {5, 6}; Line(6) = {6, 7}; Line(7) = {7, 8}; Line(8) = {8, 1}; Line Loop(9) = {7, 8, 1, 2, 3, 4, 5, 6}; Plane Surface(12) = {9}; Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{12}; Layers {n}; Recombine; } Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{44}; Layers {n}; Recombine; } Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{76}; Layers {n}; Recombine; } Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{108}; Layers {n}; Recombine; } Physical Surface("inflow") = {124, 28, 60, 92, 25, 57, 89, 121, 75, 43, 139, 107}; Physical Surface("wall") = {64, 32, 96, 128, 68, 132, 36, 100, 71, 39, 135, 103}; Physical Volume("vol") = {2, 1, 4, 3}; __________________________________________________ _ after i 3D mesh it and convering it using gmshToFoam, fixing the boundaries etc., loading the mesh using paraFoam, the inflow and walls apears great. However, there are no inside cells. It seems that the msh file does now contain the "vol" cells. what am i doing wrong ? im sure its a no brainer ps. when trying to view the mesh in enGrid im getting the same problem. Please HELP Last edited by Chapury; December 10, 2010 at 05:47.
