Hi,

The error message shows that you do not have adequate properties defined for the liquid fuel injection. Please refer to the following manuals to know about the species properties: 4.2.1. Species Information and Property Entries (ansys.com) and 4.2.2. Correlations Used for Non-constant Properties (ansys.com).

I would recommend you to use an appropriate chemkin file available in the installation directory under reaction\data\ModelFuelLibrary based on your fuel requirement. You may also use the full mechanism file and create a reduced mechanism from it. You may refer to Chapter 2: Tutorial Lessons (ansys.com) for the same.
