The cutting plane slider cuts the front off by moving the plane into the screen regardless of how the model is oriented. I suppose it would be more sensible if once you started using it, it locked its direction to the model. The loads do include a…
-
I would think so. That sounds even easier.
-
Not much, though they're much the same as constraint equations in other software. You can use them to distribute forces by making the displacement of one node equal to an average of the displacements of two or more other nodes a bit like the linkage…
-
Good point. I'll try to move *MATERIAL to after the sets and surfaces. Section cards should already be there. *EXPANSION should be written for isotropic materials in axisymmetric but only if there's also a thermal stress defined in Mecway. That co…

Pyramids are currently a problem and I don't know a practical solution sorry. Version 6 will export them as collapsed hex elements which are OK for CCX but it's hard to do that by hand. Correct that convection isn't currently exported but you coul…
-
What happens is as you suggested in point 1 - there's a temperature difference across the element and the heat flux is calculated from the nodal temperatures so it ends up being non-zero. This is just discretization error and it would approach zero …
-
Not yet sorry. The next version (6) will do this though. For now, you would have to save as .inp then run CCX directly. The save step is still a manual process tough.
-
Great idea though it'll be low priority.
-
Use a displacement constraint. Typically select the row of nodes along the edge you're constraining then apply it. For shell elements, you can apply it to the edge "face" so that it's retained through mesh refinement.
-
Penetration is unavoidable with this type of contact. You just have to reduce it to an acceptable level. Do that by increasing "Slope of pressure-overclosure curve K", perhaps by an order of magnitude at a time until the penetration is acceptable. …
-
Here's a slightly simpler and probably more correct way from what I suggested before. It's a single thin element between the beam and the solid. It's joined to each with bonded contact. The bonded contact between the beam and this thin element sprea…

You don't need to explicitly define conduction since that's the function of the elements that make up the mesh. It's also determined by the thermal conductivity which you can specify as a material property.
-
It looks like you haven't added ontact (CCX), which is under Loads & Constraints. You need to use that to explicitly tell it which surfaces might contact each other since it defaults to ignoring contact otherwise.
-
They are 3 node elements that can be curved and have quadratic interpolation along their length. They can be used for: - Beams with the CCX solver - Fins in thermal analysis with the internal solver The internal solver doesn't have 3-node beams bec…
-
It should be OK. See this example.
-
Oh I see. 3-node beams aren't supported by the internal solver. You should also clear any other red errors in the outline tree that can be ignored with the CCX solver. If it says "Solver did not produce an output file", click "CCX output" to see th…
-
Not directly but you can make a defacto template file which is a model containing an unused material or load that has some data using the units you prefer. Then when you start a model, start from that file and it'll have set the default units for su…
-
That screenshot shows the internal solver, not CCX.
-
You'll need to use the CalculiX solver for that. 1) Download and install it as described in Chapter 14. You can get it from bConverged http://www.bconverged.com/data/content/CalculiX_2_10_win_002.zip or ddfem which is easier to sets up because it…
-
If I understand you right, it sounds like they're not connected together. You can use Bonded contact for that. If they're supposed to be initially separated but come into contact when the pressure is applied, then you need a nonlinear analysis with…
-
That does indeed look like a bug. Thanks for reporting it. I'm able to reproduce it using the files you sent me for a previous issue.
-
Thanks Sergio. If anyone else has suggestions for reports, please add them to this thread. No schedule for version 6 but I expect it to be mid 2017.
-
Could you list the information that you want in a report? I'll compile it along with anything else I find to use if/when I add that feature. So far we have: 1) "Add screenshot to report" button you just described 2) Material properties 3) Mesh stat…
-
No, it doesn't allow laminate materials on solids. You'll have to do what you're doing, though you can make it a little easier by reusing the same material definition on several components, even if they're oriented differently. Material(1)-Material(…

Move/Copy isn't working here because the cylinder's axis is offset from the global axis. The coordinate system used by that tool uses the same origin as the global coordinate system. I forgot to mention this limitation in my first reply. Versions 3 …
-
What menu items did you use to change the radius? There are several ways that should all work for a cylinder aligned with the global coordinate system. 1) Mesh tools -> Move/copy, coordinate system: Cylindrical. If you choose the wrong axis here…
-
The geometry view shows the back (typically the inside for a solid) of each surface in a darker color than the front so even if they weren't all aligned in Solidworks, you could see which ones were facing backwards and put a negative pressure on the…
-
Yes, a traction also applies a moment due to the shell thickness as you pointed out. No, there isn't currently a way to define a position dependent traction using the internal solver. There is a position dependent normal pressure that you can defin…
-
That's a good point. Neither open cracks or model edges is really bulletproof for this kind of subtle interior problem. I'd like to add a more powerful tool in future. Another way you might catch it is with: 1) Select faces mode 2) Show element su…

Great
