An easier way would be to use the CCX solver with Mecway version 6 and line3 elements (Mesh tools -> Change element shape) which can be circular tubes. Here's a simple example. Be aware that the beam elements won't capture local buckling like s…

Thanks for those answers Sergio, and the suggestions Andrea. I'll just add a little rationale: I don't intend Mecway to be a tool for making .inp files. Rather, a self-contained FEA program that can optionally use the CCX solver. That means the .i…

Cyclic symmetry is a bit fussy about having other constraints on the symmetry nodes. Some combinations are allowed but some aren't. The slave nodes already follow the masters so there's no need to constrain them.
-
1., 2. That's OK to delete the unused sets. > I think the *CFLUX section is the internal heat generation, but I could not understand why some of the values are negative. When I add up all the figures they add up to my total heat flux in watt…

Yes, you'll have to use Mesh tools -> Merge nearby nodes. In general, to see if elements are joined together properly, use View -> Open cracks.
-
These more complicated .inp files aren't fully recognized by Mecway and show an error message on Analysis settings after you import them to identify what was missed. To include the extra step via Mecway, paste into CCX -> Custom step contents lik…

Here you go. The solution contains two steps - one with each direction's displacement.

1. I don't know how besides using a real shape and setting the geometry to achieve the Ixx and Iyy values you need. 2. Either A) Use a pressure load with a formula for the linear function such as -1500*y if you want 1500 lbf/ft^2 at…

Currently, the only practical way is to generate the band using Mesh tools -> Rotate/copy and check the Rotate element axes box.
-
This is what flexible joint on beam under Loads & Constraints is for. It can be a bit tricky to select the beam end faces it uses, so here's an extract from the next version's manual showing how.
-
Unfortunately *FILM doesn't allow you to use a predefined surface like that. It needs the individual faces to be defined directly in the *FILM block. If all the faces are the same face number of each element, then you can use an element set inst…

Most of the CCX information will be assuming Linux but defining steps and just about everything else will work just the same on Windows. The difficulty might be doing it through Mecway. For multiple steps, that's not really easy so it might be bette…

I don't know enough to comment on these results. For anyone else looking at this, there is some further information about the same issue in this CalculiX forum thread: https://groups.yahoo.com/neo/groups/CALCULIX/conversations/topics/13225

The TIME DELAY parameter should be on the *BOUNDARY card, not *STATIC. You also need a *AMPLITUDE that explicitly specifies the ramping to use with TIME DELAY. The solver shows a couple of warnings which are hard to find buried between all the …

It looks like the Arial font is missing. Some things to try: Control panel -> Appearance and Personalization -> Fonts -> Font settings -> Restore default font settings Look in the folder \Windows\Fonts and see if Arial is there and…
-
I think the problem is that the contacts may be initially open so on the first iteration, the force has no constraints to provide any reaction and pushes the plate off to infinity. I checked this by putting a fixed support on a small part of it and …
-
Hello student The piezoelectric capability of Mecway is currently only for static analysis, so it won't do vibrations yet. You might be able to approximate it by doing a dynamic response analysis with a non-piezoelectric material to find its respo…
-
The tensile strength is only 0.35 MPa according to the material definition so it seems to be failing just right. Maybe that's a typo? *USER MATERIAL,CONSTANTS=2 35e10,3.5e5 For a fixed displacement, please see the PipeClip.liml sample descr…
-
It's probably because the material near the supports has broken. The graph shows it's tensile stress suddenly exceeding the limit so it probably loses strength in all directions when that happens. I tried moving the supports up to the steel part a…
-
Yea, the extra parts are just to transfer the load. If it's too stiff, it will artificially stiffen what it's attached to. There's no general correct way to make a distributed moment because it depends on how the load is really applied - if it's thr…
-
Here's the .liml file I didn't attach.
-
This one works. Changes I made were: * Added a *SOLID SECTION block to link the *MATERIAL to an element set. * Added a layer of ordinary linear material on the top so it doesn't fall apart when it goes into tension. This represents reinforcement. …
-
Here's an example. I had to use TIME DELAY to get the load to continue where it left off. Not doing that would cause the load to start again from time 0 at the beginning of the 2nd step. That might be what went wrong in your case. The .frd file it…
-
Maybe more like *Step *Static,Direct 0.8, 0.8 *End Step *Step *Static,Direct 0.01,0.1 *End Step
-
I see, thanks. It depends how it's being loaded. Are you interested in bending, shear, or torsion? For a rough first approximation of shear strength, I would put a Y-direction force on the end face of the spline's shaft. But this could be wildly o…

Mecway 6 Beta 2 here http://mecway.com/download/mecway60beta2.msi The main change is the paint selection tool is split into two tools - one for paint selection and one for selecting all the way to the edges of the mesh.
-
Could you please also attach the shaft.step file? The geometry doesn't get included inside the .liml file until you mesh it. Liml files without solution data compress very well so zipping can help if it's too big. Not having seen the geometry, it …
-
1. See other post 2. You can leave all the analysis settings at their defaults of 0 or default. If you need time-dependent loading, then specify time step information. 3. In Mecway version 5, the error messages are for the internal solver, not…
-
I think you need two step sections (*STEP) for this. The first to get it started and make a single step to time 0.8, and the second one to produce the results you want between 0.8 and 0.9.
-
This example is in the test files called concretebeam.inp. I solved it and it looks like the tensile stress on the concrete part is much lower than the compressive stress. There's currently no compression only material in Mecway. I think you ca…
