Basic Doubt
 
I'm new to ICEM. I was trying to do a simple 2-d meshing to do a flow sim over a square block just to get accustomed to the meshing process.

I followed the steps given in the 2-d car meshing problem given in tutorials and got a mesh.

Now the problem arises when i try to improt it into Fluent.

I get the mesh read and everything( exported as nastran file and imported in fluent ).. But only 1 zone: interior + exterior ( the outer rectangular domain that I specified enclosing the square ) and the square itself.

No conditions / edges available for inlets and outlets.

Though I can use grid -> split to get this , I want to do this name / zone assigning in ICEM itself.


I did what was given in one of the other posts regarding setting solver and boundary in output tab , but no result.. clicked the rubic cube after setting solver to fluentv_6 and set boundary condtions.tried to import the case to fluent it says access violation.

Here again , I'm confused..to what am i supposed to give boundary conditions??? the geometry I created or part->create part -> different parts with each corresponding to a Boundary and then BC???

I tried both and still no results :D


So , Can someone tell me what exactly I'm doing wrong..

And plz tell me the step by step method...right from creating geometry to blocking to meshing .....etc.... exactly what is to be done in each step..


And kindly do not refer to tutorials...I have been struggling with tuts for almost a month now




I CAN create meshes...what I need is a method to name the boundaries / edges...and retain the naming after I use file-> export mesh

Or something similar hich lets me access these named edges as such in fluent.
