finite element method – How to mesh a cylinder with helix points?

Another method to achieve helical mesh.

m = 15;
ParametricPlot3D[{Cos[u], Sin[u], v}, {u, 0, 2 \[Pi]}, {v, 0, 
  2 \[Pi]}, MeshFunctions -> {#4 + #5 &}, Mesh -> 2 m + 1, 
 Boxed -> False, Axes -> False]
ParametricPlot3D[{Cos[u], Sin[u], v}, {u, 0, 2 \[Pi]}, {v, 0, 
  2 \[Pi]}, MeshFunctions -> {#4 + #5 &, #4 - #5 &}, Mesh -> 2 m + 1, 
 Boxed -> False, Axes -> False]
ParametricPlot3D[{Cos[u], Sin[u], v}, {u, 0, 2 \[Pi]}, {v, 0, 
  2 \[Pi]}, MeshFunctions -> {#4 + #5 &, #4 - #5 &, #4 &, #5 &},
