[ANSYS Meshing] Help Generating Multiple Surfaces as a Multibody in Ansys Fluent

twolf59 · September 21, 2014, 20:47

CFD Friends,

Im trying to create a 2D model of a pipe with cross flow along with a transverse pipe injecting fluid into the main stream. My issue is that I draw multiple sketches which define areas of different mesh densities, but when I "create surfaces from sketch" for each sketch, Fluent combines them all into a single surface, and I am unable to define the individual mesh densities I desire. Does anyone have any suggestions for how I can fix this? Maybe an alternate method?
Here is an example of what I mean, http://imgur.com/crGFTGu
While these are 4 different surfaces, DM automatically combines them into a single surface, and thus cant control individual mesh quality.

Thank you

I think you don't change "add material" to "add frozen"!
I guess with applying this change, your issue will be solved!

Thanks. in the "Surfaces from Sketch" I had to change "Operation" from "Add Material" to "Add Frozen". Thus I was able to generate multiple bodies.
