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&#8217;m not able to read the error message. Can anyone help me with this.<\/p>\n<p>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&#8217;t really understand the meaning of.<\/p>\n<p>[&#8220;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.
