Hello, 

Please ensure that your mesh does not contain polyhedral or adapted elements. The reference conditions and material type (Air) should be suitable for icing conditions. Here is a reference to a simulation: ANSYS Fluent Icing: Conducting a Fluent Airflow Simulation on Clean NACA0012 Airfoil - Ansys Knowledge

 

I hope this helps.
