ANSYS offers special axisymmetric elements that can be used with non-axisymmetric loads. Harmonic PLANE25 and PLANE83 elements belong to this group but they are legacy elements and ANSYS recommends the use of general axisymmetric solid elements SOLID272 and SOLID273 respectively instead. However to utilize them you will have to make use of scripting.
If you are using Ansys MAPDL, then just issue this command to define the elements and then model as usual: ET,1,PLANE25.
See VM43 for a MAPDL example (verification manual)
In WB you could probably enter a command snippet, but I have never used these elements there.
