4) No end in sight, so hopefully a few more decades or it becomes obsolete such as if cloud computing properly takes over or people stop using Windows. Mecway's existed for about 10 years so far and before that, it was LISA which was first released …

Answers: 1) Yes from some customer reports. 2) The non-commercial license is no longer available. 3) You can install and activate it on both but just use one at a time. 4) No succession plan. 5) Yes I intend to allow you to select a subset of s…

Sorry for all the frustration. I turns out that removing the note about beams and shells from stress in element coordinates created unexpected problems like this. "Field variables that it depends on exist -- NO" seems wrong. I think it should say Y…
-
@dculp, Yes you can do dynamic response with beams in CCX but need to address those 3 error messages you posted. Giving the beam density also gives a rotational inertia to the free node so either way is OK but density is less pure because it alters…

Hello NoahKatz It should show the STEP file if you click its name in the outline tree or the "Geometry" branch. You can apply constraints to the geometry either before or after meshing. Right click on a surface in the geometry view and pick Loads …
-
That'll be due to lack of rotational inertia on the free node as well as no 2nd moment of area of the beam. You can add an arbitrary large value for 2nd moment of area and low rotational inertia (under Loads & Constraints) to put the bending mod…

A workaround is to put a decimal point in it like 205000000000.0

@Sergio > is there a way to add an option to the importing of UNVs meshes from Salome to convert the groups of elements in components? Script here https://mecway.com/forum/discussion/comment/6377/#Comment_6377

I agree with prop_design that it's probably not actually calculating stress if you removed all the stresses from the solution tree in Mecway before solving (which tells CCX not to generate them). Those messages don't seem to consume any time so perh…
-
Delete them from any mode in the solution tree, including any derived stress like von Mises and any formulas that refer to any stress variables.
-
@JMF11, @prop_design, with quadratic elements, you have to also move the midside nodes, not sure if that was the problem.
-
There seems to be a problem with v17 importing CCX solutions slowly when you have formulas. It might be a bug re-evaluating the formulas multiple times, I'm not sure yet. Thanks for confirming it and I'll sort it out for v18. Sorry about that regres…
-
Yes, only for thin-walled, and yes it's used by the internal solver for torsional stiffness, but not by CCX.
-
@prop_design 6x displacement is dynamic, looks like you changed to static where I also see 3x difference. Good idea to get agreement in static first. I also get good agreement in static using tri6. @JMF11 line3 is to get proper continuous connectio…
-
A couple of likely problems: Tri3 elements are the worst kind of shell and may be overstiff in bending with CCX though the internal solver should be OK with simple flat geometry like this. You should normally only use them to fill gaps in quad-domi…
-
It can't automatically run several analyses. You can combine loads in different combinations by using a separate configuration for each case. Suppress the unwanted loads in each configuration. You can write the factors directly into the loads usin…

Directional lighting's still useful for the solution even though it interferes with the colors. Without it, 3D shapes are very confusing - they just look like featureless 2D projections. The other light sources are there to reduce the extremes betw…
-
This bug is a separate effect from the lighting since it appears with a flat surface where the lighting is uniform. It's caused by a different separate light source for the gradient plot, I think ambient or generated from the surface color itself. N…
-
The problem with the first model was that the shells have no drilling DOF so their nodes can't take moment loads about the normal direction. Another approach, besides the node-surface coupling that you used, is to apply the moment load to the 2D fa…

@FEA_Stress, the English one is included in the installer. I haven't updated the web pages for v17 yet.
-
Hopefully before the end of 2022.
-
@Mishal I've wondered about this sort of thing, but it gets difficult at the connections between elements when they're not colinear. CCX does this with quite complex and buggy MPCs as well as deforming the expanded elements to fit each other. It's q…
-
Hello @dculp You were quite right that the colors are being interpolated badly. I hadn't understood that there was a better way but there is and the version after next (v18) will have more sensible interpolation that includes the two extreme colors…
-
Oh, that's certainly wrong. It looks like this bug affects the other color scales too but it's most prominent with greyscale. I'll fix it for the release after next. Thanks for finding and investigating it so thoroughly.

Here are details on how to change the temporary folder's location: https://mecway.com/forum/discussion/comment/1455/#Comment_1455

I'm not sure why but @disla here shows how to build up more complex shapes using offset beams: https://mecway.com/forum/discussion/comment/6229/#Comment_6229

If the model is big enough, it switches to out-of-core mode which uses temporary files. They're put in a folder that Mecway creates when it starts and deletes it when it exits. It's located in %temp% and named like MecwayInstance######### where # ar…
-
The MITC shell elements are available in the current version (16) but they're not labelled as that since they're not optional and have replaced the old ones.
-
Good stuff. I'll see about getting it to read all the values. Usually these extra variables aren't available in formulas, but you can access them from a script which can also generate a new solution variable similar to what a formula does.
