CFD model technique?

[hed_spase]

I have a sheet metal enclosure assembly, and we want to do a cfd on the airflow volume enclosed by it.


Is there a way to easily create this volume?


thanks,


Allen

Do you want to export the volume to your 3rd party CFD package, or are
you looking for the enclosed volume for some other calculation?
Maybe something else is your goal. For either of the two things
listed above, I would assemble the part into a dummy assembly and
create a part to fill in the enclosed area. You can then use a
model analysis of that part.



If your goal is different, please elaborate, and I will help all I can.

I have frequently had to model the voids inside an assembly for CFD. Make a part called "AIR" and give it an overall size & shape of your finished assembly, then subtract (intersect) the other components with it so you are left with just the internal voids. You may have to model inlet and exit volumes too depending on your CFD requirements.

Thanks for the info.


I used to do a similar thing when I worked with SDRC Ideas. I used a boolean subtract. I just didn't know if they had the same operation in ProE (very little experience)

What CFD software are you using?..... I can help you if yo have CFDesign..

hi i am trying to import my Pro E assembly into cfdesign,
but i dont know how to create the domain or volume on which
i can specify the boundary conditions in CFdesign

i created a hollow rectangular box around my assembly to
specify the domain, however as it is a volume both sides of
it get selected seperately as surfaces

can someone help me.. my project is due in a weeks time!

kumu,


Upload a picture of your model. If you have the latest version of CFDesign and have it installed such that there is a pull-down menu in ProE, you might be able to launch CFDesign directly from ProE, and it *can* automatically cap the openings and create the fluid volume. This is spotty, tho as it depends on model complexity and robustness.


If you sharea pic, or even better the model, we could get you running CFD by the end of the day.


I prep models for CFDesign in my sleep.
