It's for linear and nonlinear dynamic response 2D and 3D and both solvers. But it turns out there's a bug that disables the input for Nonlinear Dynamic Response 3D. Thanks for finding this! It still works but you have to change to one of the other …

The next version (14) will have a stress-strain curve. Could you two, and anyone else here, tell me if you prefer the strain input to be plastic strain (0 at yield) like CCX does or total strain (yield strain at yield)?

To create a spring and damper between two nodes: * Make a line2 element: Mesh tools -> Create -> Element. * Put it in a separate component: Right click the element, Add elements to new component. * Give it a spring material: Right click…

No worries. There's a lot of things that can go wrong.

_mod2 has two copies of the force.
-
I've seen that happen occasionally too and don't have a proper solution. Changing the refinement around the hole edge such as with with Min. number of elements per curve can change whether it happens or not though. In my experience, the options ord…

Thanks for sharing this.

prop_design has a good point. It sounds like either the whole structure might be constrained too much or some members might be underconstrained causing 0 frequency rigid body modes.
-
I don't understand how that would work, but if it's simply a matter of having ipy.exe installed with Mecway, that should be no problem. Is that all it needs?
-
OK
-
It's a bit strange because typically the lowest frequencies are the global modes. So make sure what's happening is reasonable for your structure and not a bug. Then to do it the "dumb" way, increase the number of modes until you can find the ones y…
-
I don't know, sorry.

Unfortunately, imported modules don't have the global variables and they aren't part of any library or module that you can import. A workaround is to add your own mw variable in the imported module from the importing module before using it, like th…
-
If I understand you correctly, then no because it depends on the Mecway application running to access its internal state. Perhaps that would be possible by having a wrapper Python (even Python 3) library that starts an instance of the Mecway applic…

Hello RICYTEACH The API is still limited to the types of operations listed in the manual but getting component names from element numbers and vice versa will be in the next version (14). There's an undocumented function for the path of the current…
-
Thanks for the update. I've been a bit unsure of it because Guido said something wasn't right yet. Maybe that was just the shells?
-
Oh, I see who you are now. Hello again! CCX allows you to chain several analyses together in steps which sounds like what you're asking for. But I don't think you need to do that because nonlinear dynamic response already includes buckling and pla…
-
Hello Inq The more powerful way is to use Nonlinear Dynamic Response 3D as the Analysis type. But there are a couple of limitations: * The solution doesn't have acceleration so you might have to calculate that from differences in velocities betw…
-
This feature often causes confusion and I'm not sure what to do about it. The pinned support is distributed over the whole selection using constraint equations and does what JohnM said. It only reduces to ux=uy=uz=0 for a single node since that has…
-
I can't offer much help with that except to say that it runs IronPython from a dll like you found so Mecway.exe is the python interpreter executable. You can probably find ipy.exe somewhere else and it might work with Mecway but it won't be able to …
-
It looks like you already have materials named Stahl and Rotguss which are conflicting with the new ones. Use different names and remove any Mecway-defined materials from the components that are getting the new plastic material. Don't forget to ent…

You can enter a piecewise stress-strain curve in CCX -> custom model definition. See the manual section 13.1 Custom model definition for an example using 3 points.

A later one is here. https://mecway.com/forum/discussion/comment/4255/#Comment_4255

I'm not sure if you're using the internal solver or CCX. prop_design's answer is more relevant to CCX where thicker shells can perform better because they're expanded to solids. With the internal solver, thinner shells are usually better and "thin"…

Hello rpalinka Are both parts still fully constrained after removing the displacement? If not, there may rigid body motion preventing it from finding a path to a solution. Some ways to solve it: Add a constraint though an artificial low-stiffness …

The CalculiX .inp format is almost identical to Abaqus and Mecway can export that as well as import simple files. Some of the people working on Mystran and pyNastran are trying to make a converter from .inp to .bdf/dat. But at the moment, I don't t…
-
Thanks for the suggestions Clearline and Sergio 1) Unlikely because of consecutive node numbering which makes this tricky. 2) No. Although you can get it to save the solution to a separate file with Analysis -> New save after solve. 3) I'm expec…

Yes, it may be correct that the final converged step is the limit of stability. From your list of times, that wouldn't be 9.771 s because it subsequently backed off from that. However, I'm not sure that's safe. Some other things to consider: Don't…

No, sorry.

For case 4 Solution -> Surface integral then select heat flux X and External_surface and click Evaluate.
