Hello everyone,

I need to define the velocity inlet in my project. I'm simulating a biofilter.
The geometry of the biofilter is a hollow cylinder with thousands of pores. I create an STL with all the "covers" of each pore and now I need to define the velocity in radial axis.

I try to define velocity ,but only show me in one direction or axis (images attached)

                                                 boundaryField 
{ 
  ...
 
    inlet_lecho 
    { 
    type                  cylindricalInletVelocity; 
    axis                  (0 1 0); 
    centre               (0 0 0); 
    axialVelocity      constant 0; 
    radialVelocity     constant -0.134; 
    rpm                    constant 0; 
    value                  uniform (0 0 0); 
    //type                 surfaceNormalFixedValue; 
    //refValue           uniform -1.817;  

    }     
 
    outlet_lecho 
    { 
        
    type                     cylindricalInletVelocity; 
    axis                     (0 1 0); 
    centre                  (0 0 0); 
    axialVelocity         constant 0; 
    radialVelocity        constant -0.134; 
    rpm                      constant 0; 
    value                    uniform (0 0 0); 
    // type                   surfaceNormalFixedValue; 
    // refValue             uniform -1.817;  
  
    }     

....

I really appreciate your answer, I need to make the velocity goes inward the cylinder

Regards!
