Replies: 30 flow over a cylinder 2D Views: 5,164 Posted By behrang2009 Saving a particular profile and load it in another case Hi I am running a case for which I need to give Fluent an initial condition. My question is: Can I save for example density throughout a case and load it in another case with different boundary...

Replies: 30 flow over a cylinder 2D Views: 5,164 Posted By behrang2009 Problem with flow rate enthalpy sign I believe you can help me with this. I put some Lines (from the menu 'surface-line') on my model in order to monitor the enthalpy flow rate. I use the flow rate integral which is integral of...

It's obvious that laminar model is the solution for NS equations since NS eqn's are based on the notion that the fluid is Newtonian. But Mesh Generation, Run time, and sometimes round-off errors are...
