You could use constraint equations. I don't quite know the answer but here's an approach similar to what bonded contact uses but without coupling rotation: Start with the nonlinear constraint that the initial distance between the nodes is equal to …
-
In some cases, you can select the longer edge and use Mesh tools -> Refine x2 to split it into two. For edges where the ratio of number of elements isn't a power of 2, you could apply that to a subset of the elements and move the nodes around to…

> I was able to open the ".frd" directly late yesterday, but the model looks like an origami project gone wrong. From that description, it sounds like the 3-digit exponent problem which happens with some builds of CCX (possibly including the on…

Not guaranteed. Mecway only supports some common DXF shapes as listed in the manual. Though a structure like this is probably going to become LINEs which are supported.
-
Several things are unclear: Is it the internal solver (not CCX) that can't solve, or is it CCX run through Mecway? I'm concerned if there are models that can run in CCX from the command line but not through Mecway. How are you opening the .frd fil…

DXF would usually work for this but apparently SW didn't export 3D DXF in 2011 but maybe does now? https://forum.solidworks.com/thread/50774 Here are some suggestions for exporting a list of point coordinates. You would be able to import that as t…
-
My basic understanding of MFRONT is that it generates a dynamic library for a user defined material, which CCX links to. Is that right? I imagine you could already use it with Mecway by entering the material card in CCX -> Custom model definition…
-
You're right that you don't need to do the thermal analysis first - that's for obtaining the temperature field in cases where you didn't know that in advance. While not a tutorial, the VibratingMembrane.liml sample file described in the manual uses…

I don't think TIE is right for this because, as you found, it moves the nodes before solving so it doesn't impose any stress. The moving of the nodes isn't a feature for when you want to move things. It's there to make up for a shortcoming of the TI…
-
I suppose element thickness in the direction normal to the surface but really it should be the thickness of an extra layer of imaginary non-space-occupying elastic material you can put between the surfaces without worrying that it'll deform signific…
-
Making linear tets and converting to quadratic with straight edges is the same as what the automesher does when Fit midside nodes to geometry is turned off. It's off by default because it tends to make bad elements with the default element size sett…
-
In this case, you can ignore the error message and leave the von Mises failure criterion active for the CCX solver. The error message is just trying to warn you that it won't be used. I see now that it should be more clear that it's simply going to …
-
I don't know much about this method so it's hard to say at the moment. I've added it to my list but it seems like low priority. Version 8 should have a formula function in the postprocessor which might enable you to set this up yourself from the loo…
-
Any luck with rigid body? I see what you mean about reading the manual. It explicitly says shells aren't allowed so I've added an error message to Mecway if you try to use *TIE with shells or beams. I did find that it seems to work OK as long as t…
-
There's no special material for reinforced concrete. You might be able to simulate it using a laminate. I don't know how you'd convert rebar to an equivalent stack of orthotropic materials though, or even if it's possible in general.
-
I'd like to isolate what's going wrong here because it sounds like a general problem. If you can post or privately email me the .liml file, that would be helpful. Maybe I need to put in some warning about this.
-
It's probably too coarse a mesh. The yield calculation is done at the integration points inside the elements but the displayed stress is extrapolated to the nodes so it can be higher. Von Mises stress exceeding the yield stress frequently occurs for…
-
Would it help if there was an option to generate .csv with the localized Windows decimal,thousands,csv symbols? I suppose commas and dots are a problem there too?
-
Have you tried increasing the tolerance to bigger than the 2e-2 (m) distance shown in the error message? The tolerance it identifies is kind of weird, I suppose that's the automatically generated one? Or, if you use the non-TIE option, it allows un…
-
OK, I've confirmed this is a localization issue that appears when the number grouping separator on Windows is set to ".". It'll be fixed in version 8. Thanks for reporting it.
-
Problems with displacement shouldn't affect the solver progress display. Could you post an example file, German? It gets the progress data by parsing the CCX standard output (as shown in the "CCX output" box). It's possible that the format is diffe…
-
Sounds like something for a command line option. I'll see about adding that for version 8.
-
OK, it'll have both at the same time.
-
I just noticed the Young's modulus seems to be too small - 275 MPa, not GPa. If that's not it, could you attach the liml file for the single bar?
-
Looks alright the way it is. Two things I'd check just in case: 1) Displacement is getting a bit large compared to the thickness of the members so it's a good idea to do a nonlinear analysis. The two supports might end up loaded in tension (towards…
-
OK, thanks for your help. I'll have it optionally generate the ZZ von Mises, Tresca and principal stresses as well as the tensor components. And off by default because of these odd errors and not working with tet elements.
-
Since you're always going to do further calculations on it, maybe instead of showing any ZZ stress values, it could calculate the error itself and just show that? Or error + 6 ZZ stress components so you can verify it by hand. I wonder though, why …
-
I'm working on this for version 8 now. Can you tell me if this way would be suitable? Von Mises, principal and Tresca stresses would be generated using the ZZ stress components if they exist in the solution and the regular stress components otherwi…
-
I don't think Mecway will ever be good for that workflow: Open .inp -> edit -> save .inp -> solve because its internal format for everything is so different. The .inp import is mainly for meshes and a lot of the less common cards are missin…
-
For the first problem, you're right that it could have solved it but didn't. Mecway is currently more restrictive than CCX in cases like this where the it's complicated to determine if the CCX rules are being satisfied so it errs on the safe side. T…
