Thanks for the suggestion Hengre. I understand the value of easily renaming something when it's created, but there's a trade-off with adding an extra thing to click if you don't want to rename it. Since others haven't asked for that, I probably won'…

I see. That's a bit tricky. Mecway only brings the component information over to the solution when it's solving. You could try to fool Mecway into thinking your .frd file is the one from its own CCX solution and getting it to "solve". When you use C…
-
Mecway doesn't have a proper exploded view, but there's View -> Open cracks which makes each separate part shrink to reveal the gaps between them. I'm not sure what cgx results.frd input.inp does but if you want both files open at the same time …
-
Great. Changes you'll need to make are: * No variables so you have to explicitly enter the values of d_c and H * No curly brackets. Use round brackets. * Dot for decimal point instead of comma * Only enter the right-hand-side with no equals…

When bonded contact is just hanging on by a few points, it's probably because the master and slave surfaces are the wrong way around. Here, it looks like the blue part has a finer mesh than the purple gasket, so the blue should be the slave. Similar…
-
Correct, the internal solver doesn't support thermal contact conductance. I don't see any reason it wouldn't be possible with axisymmetric elements in CCX. It's just that Mecway that doesn't have them. You could do what CCX does internally and revo…

You can specify pressure as a function of position (x,y,z). So if you can express your pressure distribution as a mathematical formula (possibly piecewise) then enter that in the pressure load. Part of this formula would include calculating angle fr…
-
Oh, great. For the failure to converge, have you tried a linear analysis? That can pick up unexpected rigid body motion that's a common cause of convergence failure.
-
Not in Mecway, sorry. Though you could use CGX to open the .frd file and the copy command with the mir option to display the solution in CGX. I haven't actually tried this but it looks like it should work. To access the .frd file more easily, turn …

Beta updated to release candidate with no further changes except removal of the expiration date. Link in the first post of this thread. If no more bugs appear, that will become the final release of v13. Thanks everyone who helped guide the developme…

Yes, it could be out of memory that can make CCX just silently exit. The default CCX that comes with Mecway can't usually solve very big models, around 300,000 nodes with 16 GB RAM so 1.1 million is a lot. You should be able to do more with the MKL …
-
If you expect all the slave nodes to be bonded to a master face, then that warning means something's wrong - perhaps they're too far apart or not well aligned such as the nodes along an edge overhanging the other panel. For shell elements, bear in m…
-
mfem looks spectacular but none the examples I could see have the transitions between element sizes needed for Mecway or CCX. It must be for some other method or element type that allows that very easy kind of mesh where corner nodes are connected t…
-
If you just want a grid of nodes or rectangular elements at the points, rather than holes, you can do: 1) Mesh tools -> Create -> Quick square 2) Set the node coordinates of the corners 3) Mesh tools -> Refine -> Custom 4) Select rows an…
-
It's a very small element that can be hidden by the mesh lines. Check the status bar to see if more than 0 elements get selected.
-
@prop_design, when the solver fails, you can press the Select elements button in the Details window to find it. It's a poorly shaped one. I guess you'd have to tweak the meshing parameters to get rid of it, or add a local refinement. There's two lik…
-
Updated to Beta 2 with these changes: * Extra E3 parameter for laminates. Elastic modulus in the 3 direction. * No longer sets OMP_NUM_THREADS environment variable for CCX. * Bugfixes: At high DPI settings, there were misplaced controls and t…
-
If you were to use the same DXF file, Automesh 2D on lines needs a single closed loop (optionally with internal loops, but you don't have those). So remove the internal lines and merge the open ends (View -> Open cracks shows some gaps). Then you…
-
@cmmcnamara - the speed you described is about what I get for the default settings. But with all 7 speed sliders (attached picture) set to maximum, it does several revolutions per second and panning hard just makes it vanish off the screen instantly…
-
@cmmcnamara, there are no speed settings for the SpaceMouse in Mecway. Could you please measure roughly the time taken to do a 360 degree rotation and to pan across the whole screen with the controller at its limit? And also the speeds you prefer. …
-
That's great news. Not only will it be good for post-buckling, but I hope it'll also solve a lot of convergence failures that happen with contact.
-
Not sure how (von Mises) safety factor can be negative. Could you show an example? But yes, very low safety factors can be caused by badly shaped elements which tend to have greater error in stress for their size, sometimes quite extreme peaks. Ther…
-
It's the other way round (reference temperature is the initial temperature) so it will already be doing what you want. Yes, you can reverse the effect by negating the 6 stress components in linear analysis because stress is proportional to load and…
-
Oh, good point about the rotation. That itself is suspicious though because of symmetry and it might be taking energy away from the linear motion. Normally, I'd say it's not reasonable to expect the same results from the same inputs with different …
-
Does the CCX one rebound above its starting height, violating conservation of energy? I got a little bit of that with an orthotropic material but mostly it won't solve that far and I lost the special material that worked! One source of a difference…
-
I got it to bounce off the surface before it fails with these changes. Not sure if all of them are necessary: * Removed back surface of plate from contact. * Changed plate to quadratic elements. * Refined plate. * Turned on Automatic time s…
-
tk1537, I don't see why not, it just hasn't come up much. You can write the formula in a spreadsheet though and copy and paste the table to Mecway. You have to put a column of commas between the two values though.
-
I hope to add a simple option to turn on cavity radiation in future. In the mean time, here's an example doing it by hand. It's a bit of work, something like: * Make the model using ordinary radiation. * Solve. * Open the .inp file and copy …
-
I don't intend to make it a more general PDE solver like COMSOL/etc. But CCX's radiation between surfaces would certainly be a good fit. Not quite yet though. For now, you'd still have to define that by hand.
-
Oh, that's a good point cmmcnamara. I don't see a problem with that. The CCX manual has a little table listing the relationship between thermal and diffusion variables too.
