Hi Everyone,<\/p>\n
I’m trying to model the speices transport for the carbon dioxide methanation reaction in a microchannel reactor with dimension 50*0.45*0.15 mm, for which I have the chemkin format files for gas phase kinetics, thermodynamic data and surface chemistry data with extenions .inp, .db and .che respectively. However, when I try to import these files in fluent it closes abruptly with some error message but since it just closes almost instantenously, I’m not able to read the error message. Can anyone help me with this.<\/p>\n
Also, I was wondering how may I define the catalyst coated layer in my fluid domain? As it can be seen the attached figure I have created the geometry using design modeler, where there is a outer solid body and inner fluid body, I have named the outer surfaces as solid wall and the inner fluid body which is the fluid domain as inlet and outlet at the left and right end, but I have doubts about naming and defining the catalyst layer, here I have named the fluid domain walls as catalyst layer but I am doubtful about it. How can I do so, and according the geometry which I created and imported in fluent the following messages pops up which I don’t really understand the meaning of.<\/p>\n
[“At least one many-to-many mesh interface is found in the case file. Such mesh interfaces will not be available in a future release of Fluent. It is recommended to convert to the current default one-to-one mesh interfaces with the following text command:<\/p>\n

Also, I didn’t find any tutorials about setting the model for catalytic reaction including the surface chemistry.<\/p>\n
I’m bit new to ansys so don’t really about sources where I can get any help from. Any help would be much appreciated.
