Hi,

I have a solid body drawing of a component (only the solid part is there in the drawing) in which the liquid part is absent. i need to generate / extract the fluid volume from this solid body Proe drawing. What is the best way of doing this. Its like i have the proe drawing of a bottle (only the bottle solid volume) and i need to extract the liquid part inside. Only in my case the geometry is a bit more complex. Thanks in advance

I do the fluid extraction all the time, I use star-ccm+´s wrapping tool...

you can also mesh the bottle, and then coat it with glass or whatever material you define.

It ways depends on which software you use. I suggest you tell people which software you can use if you want more help! If you're using one of the main CFD codes, I suggest you re-post your question in the forum for that code.

For example, if you can import the shape of the bottle into ANSYS DesignModeler (for CFX) you can perform any CAD clean up operations needed, then use a 'boolean operation' slice the 'bottle' from a cube of material, leaving the region occupied by fluid inside of the bottle.

Best regards, andy2o

Lovely, and what is it like working for ansys these days?

I haven't a clue - I don't. Working with it can be a right pain at times...

Anyway, my post was on-topic and intended to highlight the methodology (boolean operations, chopping one solid with another) not any product. I assume every major geometry/mesh tool has similar features, although I'm sure the names change.

Sorry to upset your sensibilities - I'll watch out before using product names in this forum the future, though I think definite examples are sometimes useful.

It sounds like you need to create the fluid volume. The best way to do that depends upon the software you use & how complicated the geometry is.

Using your Pro-E coke bottle analogy, I'd iges out the fluid side surface. Then in Proam, I'd hfil the end. On more complicated pieces I'd likely use a combination of ProE & Hypermesh.
