Does anyone know which analysis you have to perform in order to get MFLUID results? Here's a quick description of my model: - Pressure vessel. - Wetted element surfaces are on the inside of the vessel. - MFLUID connections made on the wetted surface of the elements. - MFLUID reference...

@rb1957 everything you said, you nailed spot on.

@MikeHalloran yes - it's a very odd supplier relationship. i'm new to the program, and i'm still a junior engineer, but i know this is a weird (bad) relationship.

@aerodesign i can't go into any more detail about the specifics of the design. i can tell you that it does have to be the size it is, but so far as i can tell from our supplier, they didn't do any design iterations - they just chose one design and went with it. my job is to check their design...

@ rb1957: I'm an contract aero engineer trying to validate this design for use on our program. This design was created by one of our suppliers (a first of type for them). They designed it and created the FEM as validation. They have someone who has worked in FEMAP for several years, but I...

To give you an idea of the size, the span is about 6.5 meters and the chord is about 13.5 meters

I can't go into details about the program I'm working on, so I'm sorry to be vague, but this is not a true "wing" and it's aspect ratio is small. This wing needed to be broken up, from what I understand, to be easily shipped. Why is DESIGN 1 bad, specifically? I know it's bad, and I've tried...

SWComposites - thank you for the reply. My concern is that the creators of this model were being too conservative when they placed these fasteners. I do want to see the stress field in the vicinity of these fasteners, and I don't think that has been accurately captured in this model. I'm...

I am reviewing a design of a wing. This is a very large wing, and for manufacturing purposes, it has been split into several parts (leading edge, control surface and the wing box). The designers also split up the wing box. My question has to do with how they split up the wing box. They...

Hello all, I am currently reviewing a FEM. There is a critical section of this model in which two large bays are fastened together using about 20 "large" bolts. I'm examining this area because I am expecting high stresses and shear forces around the bolted connections. If I were making this...
