Using Femap analysis and CFD flow analysis in conjunction

Hi all,

I'm pretty new to FEMAP, only been playing around with it for the past two months or so, and was wondering if anyone knows how to use the flow analysis at the same time as a regular analysis (such as advanced transient or something like that). Currently, I have a simplified model that consisted of a U shaped base solid with a cantilever beam which creates a reactangular prism with a opening in the middle of it through which the air would flow. One end of the beam is constrained (fixed in place) while the other end has an arbitrary load on it which would displace that end, lowering the area in which air can flow. I am trying to have both the beam move and see how that affects the air flow, using the CFD flow analysis, at the same time but have no idea where to start. Any help would be much appreciated.

The opening in the middle is where air would flow.My basic model consisting of the U shaped base and the cantilever beam with an arbitrary load.

Hello!,

To learn how to use FEMAP TMG/FLOW take a look to my blog:

Thank you, but what I don't think is brought up in your blog that I am curious about is how I can do the flow analysis on moving parts. So how would I run the flow analysis while my beam is moving, affecting the air flow?

Then you will need to perform a transient CFD analysis and use Spinning/Translating Surface form to define a flow surface as spinning or translating: use Translating Boundary Wall to define surface movement at a specified velocity.

    • Direction Vector must be in the plane of the flow surface
