The overall structure of the file is like this: [ ... model definition ...] [ ... model definition that was used for the solution ... ] [ ... results data ...] so if the end of the file is truncated or…

For the heat flux at the boundary, I think CCX calculates heat flux at the element integration points then extrapolates to the nodes whereas Mecway does it directly at the nodes. That might be the reason for the difference but I would still expect …
-
Thanks too Andrea. Just a warning - it doesn't capture bending and twisting moments that would exist with an offset joint like this. Sergio corrected that above by making it symmetric, although with rigid body instead of distributing coupling. Thi…
-
Here you go.
-
Yes Edit -> Select nodes by number ...
-
This is because there are nodes on the slave surface of a bonded contact which are also slaves or other bonded contacts or constraints. The slave nodes aren't allowed to be part of any other constraint. You could work around this by removing one e…
-
Not easily. You could generate the relevant parts of the liml file with a script or spreadsheet. The equation: 3 = 1(1/m)×ux1 + 2(1/m)×uy2 is stored as: However, perhaps there's another way to achieve what…
-
I see. It's too minor for including any time soon though. There's also the converse problem where it should average at boundaries like bonded contact with the same material and symmetry planes.

This is the flexible joint on beam under Loads & Constraints. It's sometimes a little tricky since you need to apply it to the end "face" of a beam. See Help -> Manual -> 10.9 Flexible joint on beam if you have trouble selecting the face. …
-
Possibly, if it doesn't get too messy.
-
Sure

I see an abstract here http://proceedings.asmedigitalcollection.asme.org/proceeding.aspx?articleid=1628315 It sounds like it would be more convenient - don't make so many lines, just a small number of planes? I'm surprised someone's come up with a…
-
That sounds OK. Can you attach the .liml file and explain what's wrong with the results? An important effect is that Mecway applies convection to both the inside and outside of the pipe. If you only want the outside, it might be better to use a no…
-
Not sure if it has a name but these are the formulas it uses: σ = total stress tensor transformed so the x-axis is aligned with the SCL. t = thickness. t/2 1 / σ_membrane = - | σ dx …
-
Thanks for the suggestions. 1. I agree it is very nice but low priority. You can use left/right click on the axis triad in the corner to get 6 orthogonal views. 2. Oneday I hope. 3. You can use the "pressure" load instead of force. If you …
-
Probably not because of priorities. I suppose you can still do it using the FEA results by hand and/or with 3rd party calculators?
-
Hello. Somebody here might be able to help, but this forum is mainly for the Mecway software. You'll probably have better luck on an ANSYS forum such as http://www.eng-tips.com/threadminder.cfm?pid=569

Right click Solution in the outline tree, then choose New table or click the same icon at the far right of the toolbar.
-
Take care with OUTPUT=2D on beams. It used to have a bug that caused the stresses to be wrong. Not sure if it still does.
-
Yes, the reaction forces are already in the global coordinate system. The components aren't shown in the outline tree but they're in the table.
-
They are Tensile Force, Shear Force V, Shear Force W. Use the Element values instead of the Node values. They're aligned with the element's coordinate system but I'm not sure of the sign convention off hand except that Tensile Force is positive towa…
-
Hopefully. People have asked for this before but I can't promise since it's a low priority.
-
Probably not. Instead, I might look at changing the ordering so 2 comes before 10.
-
Possibly. What's the use for that? Because it's easier to position nodes than enter vector components, or to align it with the mesh?
-
Thanks. This is mainly because the surface isn't very cylindrical - the element faces are flat. I repositioned the nodes to be on a cylinder and it came out with a much more uniform displacement around the edge. If you need radial displacement on …
-
This is a design change that comes with the improvement of the Refine x2 tool which now properly creates transition elements between the refined and unrefined regions. A side effect is that beams get this "transition" mesh too so that their refineme…
-
Do you mind uploading the file(s) for that cylinder, Andrea?
-
Frictionless support now has a displacement value you can specify, which will be the radial displacement if you use it on a cylindrical surface.
-
I see. Yes, it can create ugly transformations like rectangular when cylindrical feels more natural but hopefully you don't look at them :P My intention with the design of it is that you should never have to think about what coordinate system the no…
-
Ah, reaction forces are something that needs a way to see the results in an appropriate coordinate system. That would be a postprocessing option though. For a sliding surface in any orientation, you can use frictionless support. If it needs to onl…
