Hi, I'm using FEMAP for FEA but obviously there are a few things to wish for when it comes to handling "messy" geometry... Anyone know a good software (not crazy expensive) for stitching and cleaning slivers etc? I'm using rhino normally but this is not one of its strengths when the model is...

Hi, I have a model that consists of shell elements (mixed composite and steel plates, extracted from outer/mid surfaces). At some locations I have overlaps of as much as three plates (at some locations the outer surface is a solid). Now, I want to model contact between these and I'm trying to...

Hi, Is there a way of plotting applied loads, i.e. a pressure as a contour in FEMAP? Let's say I have a pressure distribution (applied load) I want to view in coloured levels.

Yes, basically that's what I have. Actually I have no gaskets, only composite panels bolted to a steel frame (washer-composite-steel frame-washer). But since the stiffness is much less than for steel I guess it can be compared to a gasket. The idea is that for daily fatigue loading all in-plane...

Thanks for the replies, I can't really let go of the problem. Your arguments feels logic but I just can't prove it... What I'm looking at is a bolt connection of composite panels so the thickness of the "gasket" is quite high. If I assume for one material: F = -k*dx (a linear spring). Let's...

Does the thickness of the gasket influence the preload when temperature is changed? I have a bolt connection where everything is steel except the gasket (it is actually a composite part). Everything is preloaded so that the bolt is under tension. When temperature is changed the gasket will...

Thanks, that makes perfect sense to me now.

Thanks for the feedback. Haven't really analysed joints this thoroughly before so please bear with me :) Wouldn't FXY give only the shear component? I'm mostly worried about the normal force since the panels are mostly laterally loaded. I think what I am really looking for (at this stage...

Hi all, Is there a way to view the shear flow along edges in FEMAP? There is a function in the NEi editor called shear flow but I haven't seen it in FEMAP. It seems like a quite basic function and something that would be used all the time (welds, rivets etc). Problem: I need to determine on a...
