Stiffness matrix interpretation of the bearing element COMBI214

  I have some doubt about the element COMBI214, i have the radial, axial and tilting stiffness of the bearings which are assembled on my rotor (provided by SKF), i don't know how to convert the radial value of stiffness into the K11,K12,K21 and K22 values that the matrix representation of the COMBI214 element needs.
  
  I also thinked to introduce longitudinal springs to simulate the axial stiffness of the bearings but i still have doubt about how to consider the tilting stiffness of the bearing.
  Thank for the attention

  Recently, SKF launched a dedicated App to model rolling bearings in Ansys Mechanical. Perhaps this could help you: https://catalog.ansys.com/product/63497ec83c6398b6fea1184a/skf-bearing

  Hi Dgiunta88,
  I just contacted Ansys and it seems that there are issues with the Ansys store. They are working on it so hopefully it will soon be fixed.
