Mesh of hollow cylinder

Hi all,

I'm trying to create a mesh for a hollow tube using Mars. I have checked the Mars manual and found the following sentences to generate the hollow cylinder mesh:

Cylinder { // use ingrid convention
5 6 ; 1 10 ;
2. 2.31 // radii, center is origin in XY plane
0.3 19.52 // coordinates in the axial (Z) direction
}

Following above code, I have generated a mesh as shown in the attachment. But there is only one element in the radial direction. Also, in the above code, there is no parameter to define the mesh in the radial direction. Anyone knows how to assign multiple elements in the radial direction? Many thanks.

Best wishes,
Chenyang

In your case, "5 6" means discretize the radius in 6 elements, keep the last (6-5) element(s) to make a hole. Try using "0 6" you will see the difference.
