I have a 3-D model of a packed bed that has multiple heterogeneous reactions occurring in it. I want to be able to monitor the rate of one of the reactions along the length of the bed to validate my model. I would prefer to do the result visualization in CFD-post. Because of the size of the model, I would prefer not to use data from all the cells, and want to only view the rate of reaction along the center of the packed bed (kind of assuming symmetry).
My current approach has been to create a surface in Fluent that runs through the middle of my packed bed at the center. I then use the export data feature to export the heterogeneous rate of reaction data along the surface into a CFD-post compatible or ASCII format. However, when I take the data file into CFD-post and I try to view the data, it says that the data is "undefined" and I can't really access the values.
Is there a typical method people use when trying to monitor rates of heterogeneous reactions? Also, is there a different kind of data file I should try exporting to for CFD-post? The user guide doesn't have a lot on reaction monitoring.
