Thanks. This has come up before. It's on my list so hopefully!
-
Not easily. With CCX, you can add a *AMPLITUDE block. It's meant for time dependence, but you can just put a single value at any time (eg. 0) and it gets multiplied by all the loads that refer to that with their AMPLITUDE parameter which you also h…

I seem to remember the usual behavior when it needs too much memory is to leave an empty .frd file and abruptly exit with no error message. Don't know about the log file though. Is it that?
-
Yea, it's because of the solids like prop_design said. You can get the solution as shells though by adding this *NODE FILE, OUTPUT=2D in CCX -> custom step contents.
-
@avscorreia Yes, major versions (12, 13, 14, etc) can all be installed independently.
-
@Sergio. Yes, it's a bit of a compromise to use total strain instead of plastic strain. I've tried to make it clear in the UI to prevent mistakes though.
-
@pberry, Thanks for the suggestions. All noted. @Vinicius_Petrucci For 1.png, you can use Extrude. But maybe number of copies input in Move/copy would be helpful. What I usually do for a huge number of copies is make several copies, then select a…
-
@Vinicius_Petrucci Thanks for the detailed ideas. First suggestion: Mecway isn't really aimed at civil engineers, so I don't want to bend it too far that way. But Sergio has also asked for more convenient ways put similar material properties on lar…
-
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…
