How to vary density along one axis in Ansys Workbench

  Hello,
  
  I have a model, a MDF (Medium-density fibreboard) plate in ANSYS workbench.
  
  As you can see, its density varies along the z direction (thickness direction).
  
  I know I can divide the plate into some thinner plate with constant density but I use this plate for the transient analysis and the plate is covered with some (more than 10) absorptions layers. For each absorptions layer, there is an APDL-snippet to define the damping coefficient.
  
  If I do so, the absorptions layers should also be divided into some thinner layers. It will be a complex model.
  
  How can I vary the density?
  
  Thanks a lot!

  Hi,
  
  You can use the field variable to specify spatially varying densities.

  Hi Sandeep,
  
  I use the student version 19.2 but I do not find the Coordinate Z for density.
