Memory use can increase steadily as you use it. I know of at least two reasons but haven't ruled out the possibility of a memory leak: 1) The memory reported by Task Manager is sometimes not actually used and is immediately given up when an applica…

Hello Albert 1) You can write a script using the API function solution.mass(element_id) 2) I don't think so. You might have to re-implement that calculation yourself. Don't use the specific heat variable in the solution formula because it doesn't …

Hello DavidK It already sort of does what you're asking - Named selections and loads and constraints that are created from geometry surfaces (right click a surface in the geometry view) persist through remeshing. These are indicated by in the out…
-
Thanks for asking. I know this would be very convenient and it's on my list for features but I can't promise when.
-
No, sorry. You should be able to do it manually though by solving once to find the time at which the required temperature occurs, then a second time with a time-dependent internal heat generation that includes a step function (heaviside()) to turn …
-
Possibly. You can get position dependent heat flux on a surface by putting a layer of non-conductive shell elements on it (can be generated with Mesh tools -> Hollow) and using the existing position dependent internal heat generation on them.

I changed it to an isotropic material and the deflection is almost the same (0.3 inch) with refinement. That agrees with the formula here https://www.engineersedge.com/calculators/parallelogram_plate_edges_fixed_15142.htm which says 0.35 inch. So i…
-
Hello Peter. Some thoughts: Each layer has the same stiffness in two orthogonal directions but the layers are all orthogonal or parallel to each other so there's no effect of having multiple layers. Maybe that's because this is just artificial data…
-
The file I see has only a single element with all nodes constrained so the displacement is 0 everywhere. I changed it to make it like your description but get 1.3 inch maximum displacement magnitude, not either of the solutions you described. Sin…
-
Not sure if you uploaded the right file. This one has a zero solution.
-
Is there any gap or initial penetration there? *TIE ignores surfaces that are too far apart while the default option allows that. Or any error messages in the output?
-
Import doesn't really work better than Open, it just doesn't show the error messages. Sorry for the frustrating crash. I'm not sure quite why it happens but I'll fix it for the next version (14). Here's my conversion of pret3.inp to .liml. Use Too…

Hello Jalal 1. Your first problem is tricky. Mecway has no automatic tool to merge disconnected elements like that. Usually, you'd start building the mesh with those details in mind and have nodes positioned for them. Otherwise, you can correct it …
-
Yes, you can uninstall MKL afterwards.
-
More basic ways: A) The Python scripting is probably no use because you can't use it to set contact stiffness yet. Command line parameters Make a copy of the file for each parameter value like model1.liml model2.liml etc... In each one, add a A…

It's often easier to use solids for bolts instead of beams. You can connect the underside of the bolt head to the surface with bonded contact. If you make the solid mesh with a plane through the cross-section, you can also use CCX's *PRE-TENSION SEC…
-
The order is unspecified and might be something to do with the file system. I'll change this to alphabetical order in version 14. Thanks for bringing it up. Maybe use subdirectories to group them?
-
The source files included with Mecway 13.1 are also incompatible with newer MKL versions. Here is an update of the complete CCX source code package that incorporates the above changes as well as making it compatible with current and hopefully future…
-
It won't happen in Edit -> Select faces or Select elements mode. Otherwise, no.
-
I don't intend to add support for CCX's fluid features except possibly one or two specific bits for a special case. Otherwise it may end up with half-baked fluid capability and perhaps need new kinds of inputs, visualizations, etc. The existing flu…
-
Could you upload the .liml file? The only way I know of that von Mises stress or safety factor can appear negative is the interpolated values between nodes on quadratic elements. In that case, refine the mesh to reduce the error or ignore it if it's…
-
Hello wolland. A couple of problems: The pivot point of the compression only support is not at the end of the beam where the other constraints are. You can see this in the deformed view. That makes it not really a simple support. To correct this, r…
-
Hmm, that error message on maximum shear stress x 2 is a bit odd. But it only works for solid elements.
-
No particular reason, it's just not there. Perhaps nobody asked for it. Though you could create it yourself from the stress in element coordinates components using Solution -> New formula. Interesting idea about using pressure as out-of-plane st…
-
Those mistakes in the build process mentioned above are corrected in the current version of Mecway (13.1). Please don't use the CCX build script or instructions in v13.0 because they're so bad. But there's a new problem. GCC and gfortran were upda…
-
In your example, either value is OK because they're so similar. Anything within the same order of magnitude is basically equivalent. Same goes for radius vs diameter - it doesn't matter. If the materials were really different (eg. rubber gasket on …
-
That looks normal. At each time step, it's solving a new static problem and convergence has to begin again, so the graphs jump back up to high values. Even with quasi-static turned off, there are still time steps quietly happening in CCX so it may s…
-
@MartinB, you don't have to go through a named selection or component. Select the both-sides face selection, change to Select elements mode, then back to Select faces mode. It will be left with only the front faces selected. @prop_design. That new …
-
Yes. Although the initial conditions are quite limited so you may need to accelerate the object from stationary using gravity. Prepare to spend a lot of time on it, especially getting contact to converge. So start with a very coarse mesh and only r…

Welcome back Akos Did Z88 stop at the same deflection as CCX? At least that would seem to confirm it's something about the design, not an artifact of the solver. By wrinkling, I meant this kind of effect for membranes in tension. Probably not rele…
