Hello everyone,rnrnI have a new doubt about how the geometry is “”voxelized””. I ran the cylinder3d example and I am looking the coordinates of each material-number. I tested the example case with the default values. When the user-defined function “”prepareGeometry”” ends to give all the material numbers, it is printed the results of this processes with the function:
Code:
superGeometry.print();
rnWhat it is printed is:rn
Code:

rnThe example used a rectangular channel of 2500x410x410 mm (x-y-z coordinates) with origin at (0;0;0). Each material number is:
1: Fluidrn2: Lateral, bottom and top wallrn3: Inlet rn4: Outletrn5: Cylinder wall
rnIf we are interested just in the fluid flow, it can be seen that minimum and maximum coordinates (x-y-z) for material number 1 are:rn
Code:
minPhysR=(0.0025,0.0075,0.0075); rnmaxPhysR=(2.4925,0.4075,0.4075)
rnAs the code use the bounce-back approach for the wall (without the cylinder wall) the minimum and maximum coordinates should be:rn
Code:
minPhysR=(0.005,0.005,0.005); rnmaxPhysR=(2.495,0.405,0.405)
rnCould someone explain me why this is happening?rnrnBest regards,rnAlejandrorn
