(Solved) Turbulence model and Y+ value

Hello expert,

I am new to CFD and i have some questions about turbulence model and Y+ value.

  1.  There is a lot of turbulence model provided in AcuSolve: Spallart Allmaras, K-epsilon, K-omega,...
    - So which model should be used for some specified case?
     
  2.  The value Y+ is used to determined the 'first cell height' while meshing.
    - what is the value of Y+ should i used to calculate 'first cell height'?
    - Does it depend on type of flow (internal/ external) or chosen turbulence model?
     

the following picture was taken in HyperMesh > Utility browser.
