Hello everyone

I have joined recently a heat transfer project where it is difficult to take certain measurements and so we will try to run numerical simulations to better understand the temperature field as well as the turbulence distribution of the flow.
I have used ICEM in the past for meshing different simple geometries with tetrahedras, and because I am somewhat familiar with it I chose it as my meshing tool. My supervisor wants a structured mesh, however I have run into different obstacles when trying to obtain one.
First I have blocked the helical wire extruding one face along the central curve, and twisting it with a specific angle to accommodate the helical pitch. I have obtained a premesh for the entire volume of the wire(although only the surface in volume Body was needed) and transformed it into an unstructured mesh. I have attached my geometry and the mesh for the wire wrap.
Then I tried to make a surface mesh for the surface around which the wire is wrapped. Unfortunately this resulted in a mesh with elements that didn't line up with the ones of the wire, and also with elements in the volume that should be empty.
The last step I would have followed was to create inflation layers from the surface mesh of the inner cylinder wrapped with the wire to the outer surface surrounding it.

I was wondering if anyone has any suggestion on a blocking strategy for this geometry.

Thanks for any ideas
