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…
-
Yes, you can use Mecway and just install CCX as another solver. Some the the more special features won't work with CCX but plasticity will appear as a material property.
-
I see. You could use the table definition of force for that. What phenomena are you looking for? Fatigue, plastic deformation or something else? For plastic deformation, use CCX. For fatigue, neither solver does that directly. Instead you migh…
-
Can you clarify what you mean? Do you mean having several of the same force on different parts of it, or different copies of the same bar? Or do you mean a force that turns on and off with time? In the first case, not generally. If the force is ap…
-
There's some information under Shell and Beam on p52-54 of the manual. Beam tensile force and stress are positive for tension and negative for compression. Shell stress components are in the local element coordinate system, as shown by their n…

Can you clarify the problem?
-
1. I'm not sure about using laminate material to simulate reinforcement bars. One way could be to make a steel layer with the same cross sectional area as the total rebar cross section in that plane. Then the overall tensile stiffness in the directi…
-
I would use a single step with amplitude like: *AMPLITUDE,NAME=AMP_1 0,0 1,1 2,-0.333333333 unless you're planning to add more complicated differences between the steps like making one of them linear or different outputs, etc. It c…

The problem seems to be improperly connected edges around one side of the hole. Other software may be automatically healing those edges together. To find the problem, make a surface mesh (Meshing parameters -> Surface mesh) which usually works …
-
Thanks for the feedback Sergio. 1) I haven't looked into this much since I see it as an advanced option that you can do yourself by setting an environment variable. Is that right? Maybe for the next version. 2) Thanks. 3) Not yet sorry. …

For 64 bit Windows with a big enough hard drive and page file, there's no such thing as not enough memory because it can always use more disk space. So it could be that disk space or page file maximum size is too small, or it could be a bug. Make su…

Hello UGMENTALCASE and welcome to Mecway What's happening here is as Sergio guessed. There's no thickness on the shell elements. However, for this model you probably don't want to use shell elements but solid elements. For that, you'll need to imp…

I've added gap conductance to my list. Version 6 is nearly up to beta so probably no new features for that though. But it will have many of the common CCX pain points improved on.
