At which sintered temperature can get a full cubic 8YSZ?

Noman Ghulamullah

Jonathan David Sands i am working on development of 2D model , the issue is i am new to this field , as i reviewed some literature and found the governing equations for SOFC cell , now i have to solve my equations numerically with some CFD tool /software and couple with them with electrochemical model. now i have to understand what is CFD and numerical methods , discretization , how to write a code for it in Fortran or which CFD software i would start with like Comsol or Ansys. so your guidance will be helpful as now on i will develop a simple model with least phenamenas and later on extend it for my objectives .

Thank you
