Circular Assembly

  • Easy to create, largely the same procedure as for rectangular assemblies
  • Circular assemblies can be sliced to create partial circles, pie shapes, etc.
  • Easy to add float resistors, flow length automatically adjusted when the assembly is sliced or a hole added
 

Assembly Holes

  • Rectangular and circular holes are allowed
  • Hole can be centered or offset
    • polar mesh is used when the hole is large (tube shape)
    • hole center can be outside the assembly
  • easy to resize and reposition holes
  • assembly holes reduce the need to perform slicing and also reduces the number of assemblies (useful for Sauna Standard users)
 

Miscellaneous

  • Option to display numerical wattage for resistors
  • New method for distributed wattage when resizing plate or boards
    • wattage / face_area is kep constant
    • when plate size changes, the wattage is increased or decreased proportionally
  • New Toolbox calculations for heat transfer from isolated plates
    • round and annular plates
    • rectangular plate with hole
  • Complete Sauna User Manual is available through the Windows Start Menu
 

Limitations

  • Sauna V5.0 is primarily useful for modeling circular circuit boards
  • Modeling cold plates, cans and wires is possible, but is reserved for experienced users
