The distribution of the heterogeneous reaction rates in Fluent and CFD-POST are very different (see Figure 1). The units for heterogenous reaction rate in CFD-POST are in mol\/m3s. Even if it is converted to kmol\/m3s (0.001 \u0445 mol\/m3s ), the magnitude will be much less than what Fluent is giving. Also, the volume integral of heterogeneous reaction rates written in output file (using “Solution-Report Definitions”) of Fluent and that calculated using CFD-POST are matching. The same is the case for all the heterogenous reaction rates.<\/p>\n

Also, I stored the heterogenous reaction rate (included using UDF) in UDMI. The value returned by UDMI and that showed in CFD-POST are the same. <\/p>\n

Did anyone face this issue in which the distribution of the heterogeneous reaction rates are different in Fluent and CFD-POST?<\/p>\n
