I want to perform a flow analysis in a filter in ansys fluent air handling unit. How and where do I need to define the porous area. Thank you in advance for your help.n

Hello,nYou should create a separate named selection for this volume (let's call it filter) in Ansys Meshing. When you read the mesh in Fluent, you should be able to select and mark this cell-zone as Porous under 'Cell-Zone Conditions'. Please see the screenshot below.nKarthikn

Porous Jump (boundary zone) or Porous Media (cell zone) are the two options. You then assign resistance coefficients over porous area: it's all explained in the Fluent User's Guide along with ways to convert various types of data into the coefficients. n
