Density UDF for compressible liquid flows

How to define a value of BMODULUS for air or others in Density UDF for compressible liquid flows(default value was 2.2e9 for water)? Maybe this UDF is only applicable for liquids, not for gases?

Yes , I think it is only applicable for liquids,

For the calculation of air you need to change the BMODULUS , density.

Please check here,
