define zones in an imported mesh
 

I have to work on an imported mesh and doesn't find the possibility to work on it and define zones for boundary conditions.

Importing a mesh seems to avoid the working on it. It is not possible to work on the fluent mesh tool (using the workbench). I can only go a step further and open the Ansys Fluent program. The only way I know is uing the adaption function and separating the mesh. This is not the best way (one can't mark walls, only cells), exspecial when I want to define a symmetric wall.


Does someone know an other way of definig walls for boundaries

You can type 'mesh'+enter in the command window. Again and press enter. This will show you list of commands you can execute to modify mesh or mesh zones.
