Thanks all! This is exactly what I was looking for. Much appreciated for digging through the obscure MSC archives.

Hello, I am a stress analyst working in the aerospace field. I am trying to recreate an old FEA using an input deck from the early 1990s, but am unfamiliar with the language. NASTRAN is the solver I use daily. I can't share the actual file, but below is an example of the deck with random values...

Hello, it might seem like a dumb question, but how would I extract shell forces from my FE Model? I have a model made up of many 2D Shell Elements and have gridpoint forces and element forces output. I know that the shell forces are really running loads (or membrane forces). And I can extract...

Hi all, I normally work in Hypermesh, but have recently been required to use some tool that only works with Patran. I have a large model with many different properties and when I import my Hypermesh BDF into Patran I lose all the property names. They come in along the lines of "Pcomp.1" or...

How would you model a joint SWComposites?

Hi, I'm trying to calculate the bending moment/stress in a bolt in double shear with a gap between the plates. I know there are much more realistic ways to do this, like assuming that the clevis (two outer plates) create bearing/contact stresses, the use of semiempirical formulas, or methods...

Hi, I'm trying to understand the use of CBUSH elements with PBUSH properties for grounded constraints on a model. Normally I'd use displacement constraints in the 6 DOFs to constrain my model, but I recently came across "grounded bush" elements. In Hypermesh, these elements are classified as 1D...

Hi all, Does Patran have any defeaturing capabilities that would allow me to remove fillets/chamfers, or am I limited to doing this in another software, like Catia? I can’t seem to find anything. Other FEA software like FEMAP have this feature, and additional powerful solid defeaturing...

Thanks for the responses. My new title according to my company is “Engineer” (technically a level 2). I was hired two years ago as an “Associate Engineer” according to them (or a level 1). But I’ve shown that I need minimal supervision and can take in larger projects. My boss is very much...

Hello, I’m not sure if this is allowed, or belongs here, but I was hoping to get some insight on where I should be salary wise. Please remove if not allowed. I’m currently in the talks with my boss about receiving a salary increase. Thing is, I joined my company two years ago and this will be...

WARose, I definitely could do a trial sizing by hand, but I'd like to understand how it could be done using the available FEM. This is basically a keel beam in an aircraft, and the external loading is complicated, as it begins as pressures applied at the wings and distributed throughout the...

Hello, I'm trying to size this frame, which is essentially a beam fixed/pinned on either end and loaded externally. The FEM is basically a global model (other components not shown) used to distribute loads and isn't used for stresses due to its coarseness. What I have below is the frame...

Hello, I'm trying to understand how to size a structure using the loads (shell forces?) that flow through a structure. I've created a very simple representation (essentially a beam) of the actual structure (aircraft intercostal or keel beam). I know I could determine the distribution of loads...

Hello, I am new to Ansys ACP and am trying to set the element normals of a box spar using an oriented selection set. I'd like the normal direction of the top surface to point in the positive z of the rosette, and the bottom surface to point in the negative z of the rosette (so the part is being...

Hello, I'm trying to size a tension clip, but am confusing myself and fear this problem is simpler than I'm making it out to be. I have a tee shaped tension clip, and have distributed an external loading into the two fasteners. Now, my problem is that because of some asymmetricities in the...

How can I determine the thickness of a bolt plate, given the forces shown applied at the lug hole? I am fully aware of how to distribute the loads into each fastener, but then what? I know that the applied forces create (Mx, My, and Mz) moments as well as shear at the bolt group c.g. How can I...
