I do a project about simulation of calcination process using Ansys-Fluent. The question raise in my head is that if I want to use mixture model or Eulerian-discrete model, I can’t Add solid material properties ( Calcium carbonate and calcium oxide ) in mixture or discrete phase properties. If I want to define solid material properties in (Discrete-phase >> set injection properties >> material) or in mixture, I cannot see any solid material. How can I solve this Problem ?
