An additional thought - If the load should be distributed according to the area of the panel such as uniform pressure load a floor, then my previous suggestions are probably too complicated and the only practical option may be to mesh the panel exp…

The linear Dynamic Response 3D analysis type can't model buckling. Use Nonlinear Dynamic Response 3D with the CCX solver instead. You'll have to change the elements to line3 for that too. I didn't get much different a result until I doubled the for…

Load to panel nodes: * If the geometry is simple (axis aligned, not too many nodes), it may be practical to do it using constraint equations. * With the CCX solver, there's the *DISTRIBUTING COUPLING keyword which also requires you to specify t…

You can remove them with Mesh tools -> Delete unused nodes.

You can enter a function of x,y,z in a Temperature load like this:

@drose. If you mean time points for dynamic/nonlienar/etc., you should be able to do that by manually adding the *TIME POINTS card for CCX. If you mean frequency "data points" (I'm not sure what that is) in a frequency response, it looks like you h…

I agree it's a bit confusing. It means use the Isotropic option in the Mechanical tab. That's because it uses Young's modulus and Poisson's ratio from there. No UTS, sorry.
-
Thanks for testing that @dculp. I hadn't considered the cost of the stress. Looks like it may be more useful.
-
Here's an example. The changes are to replace *FREQUENCY 8 with *FREQUENCY 8, 1e8, 3e8 to limit it to modes between 1e8 and 3e8 Hz
-
Add the PU variable to a *NODE FILE block to get phase and magnitude like in the attachment. I guess you would have to transform them somehow to get to in-phase and out-of-phase components. I'm not sure what to do about the irregular frequency spac…
-
@dculp It turns out you can do frequency response by manually specifying the CCX cards. and interpreting time as frequency in the loads and solution. Here's an example.
-
I don't think this is really possible with the eigenvalue solver that Mecway and CCX use. Most of the solving time is spent finding the frequencies, and all at once, so by the time it can choose them, it's too late. CCX has options to specify a freq…
-
@Sergio I don't think so unless you recompile it. It might be time for me to look into updating Netgen more thoroughly soon. But as with a lot of things, it'll have to wait till after the upcoming release and might take me forever.
-
I'm unlikely to add CAD-like editing tools. To edit nodes/elements in bulk, you can edit the .liml file with a text editor or maybe spreadsheet. Multi-select for the outline tree is on my list but not yet sorry. Preview image is possible but low …
-
@dculp. Netgen 6 can mesh some models that the default one can't, as you've seen. But it's also slower and I think there are some cases where it does worse than the default one. There isn't really a clear advantage of the default over 6 other than…
-
@Sergio, yes it's a bit strange that you can change the CAD surfaces for a load but not a named selection. I've added that to my list but it's low priority.
-
You should be able to make a function for putting a node in the center of a circle using the Python API. I don't know the math of it, but the structure of the script could look like this: # Get the coordinates of the points that define the circle fr…
-
@prop_design, yes that's a graphics issue. For display, Mecway is just expanding the shells into prisms independently of each other, but CCX expands them into something like a frustrum shape consistent with their adjacent expanded elements. @disla,…

Hello J Eppinga If you're starting from a STEP file, you can define spherical and surface refinements that get applied when you generate the mesh. You can also specify a global maximum element size. For any mesh, there's a Refine x2 tool which doe…
-
Good news. There's an easy way to prevent the Array dimensions exceeded supported range error which can also occur elsewhere like displaying a big mesh or reading the solution from the CCX solver. Copy this Mecway.exe.config file to the same folder…
-
I used to think that too but it turns out they're still solved as single elements and only get expanded to one element per layer for the output. You may still get an improvement due to more integration points though.
-
If you do use laminates, it should be with CCX, as prop_design suggested, not the internal solver because only CCX laminates have stiffness in the normal direction. But, flat hex20 solids are pretty good with high aspect ratios. You may only need o…
-
Sorry if you're going to lose work. One workaround may be converting to quad4 if there are separate parts having no triangle elements (due to lack of tri3 shells with internal solver). Or maybe the CCX solver if you install one of the higher-memory …
-
It's part of force per length but beware that it can have huge errors. Sometimes averaging the values on adjacent nodes corrects that.
-
Yea, it used to, but it was causing problems when there was too much data, especially in dynamic response where the all the time steps can make it huge. I probably won't get it to reuse existing stress. It's a good idea but too low priority. I thi…
-
1) You can do that using a face selection instead of a node selection. It's tricky to select the faces at the connection so what I did was select Plate's elements, use Mesh tools -> Disconnect elements, hide Flange, then select the now exposed fa…
-
The maximum number of nodes depends strongly on the connectivity of the mesh. I just solved a flat quad8 & tri6 shell mesh with 973000 nodes and it was OK. But if your model has a lot of T-connections or other ways that more elements share the s…
-
Sorry about that. It's been a frustration for others too. In some cases, it shows a warning, but probably not for velocity. Hopefully I can find a solution.
-
A few people have asked for this and I hope to later but it won't be in the next version (14).
-
This is a tricky design compromise. What happens now is if there are no field variables (such as first time solving a new model), it automatically adds most of the relevant ones that can't be generated after solving, and that includes velocity for …
