Hello Pier. Here's a Mecway file to generate an equivalent .inp file. I've defined the unsupported features by hand in the CCX branch of the outline tree.
-
Thanks for the update. Good to hear it worked. Just one question though, are you inventing the light bulb? Because I think there's some prior art in that area.
-
On second thought, I forgot that we have temperature dependent electrical conductivity so you wouldn't have to assign materials element by element. Should be pretty simple as long as there aren't any severe nonlinearities that make convergence slow.
-
If the temperature is fairly uniform, that seems OK, but otherwise it's going to be a nightmare picking out groups of elements of similar temperatures to assign the same material to. It should be possible to write a Python script to automate that b…
-
@disla, yea, it just varies the deformation scale factor symmetrically between + and - some value to animate it. Mecway chooses what it thinks is a reasonable amplitude based on the displacements and geometry so it might be different sometimes.
-
Since those posts, Mecway now has folders (called groups) for loads, but still not cofactors yet. Thanks for reiterating the need for them. The Displacement and Node rotation constraints allow you to choose the DOFs to constrain in either global o…

Change to Select faces or Select elements mode and turn off Tape measure.

@LHartley For an existing mesh? Not that I know of. the .XYZ format is also for a new mesh, so the nodes won't be linked to existing elements. You can modify an existing mesh for both component assignments and node coordinates fairly easily with a …
-
@LHartley You can do that with the .XYZ file format. It's a CSV file with the 3 coordinates for each node on each line.
-
Results extraction at a given coordinate without node # Interpoloates stress XX at the point in global coordinates (X, Y, Z) = (0.5, 0, 0.5) assert mw.version() >= 18, "Wrong Mecway version" value = solution.interpolate("stressxx", Vector(0.5,0…

@Mishal. The internal solver supports all the built-in beam section shapes with Dynamic Response 3D, but not 2D. You can use 3D instead of 2D for everything except plane strain.
-
> Could it be a rounding / quantisation type issue with the colouring? You're absolutely right. I've managed to reproduce it now. There is a fudge which causes a relatively small spillover of color outside the specified range. Normally, it's not…

This error "cp: cannot stat [...] ccx_2.19': No such file or directory" or "cp: cannot stat [...] ccx_2.19_MKL': No such file or directory" means the final binary failed to be built. Look in x64/buildlog.txt and you should find error messages at…
-
I've had another think about this and it could be just the effect of the low contour plot resolution, which in your example is a single color for each element face. That single color is an average of the node values so individual nodes may be lower …
-
Yea, that doesn't look right. Could you send me the file? Possibly by email if it's confidential.
-
Oh, Guido must have fixed that. Yes, should be fine to update to at least CCX 2.19 or 2.20. I still use 2.19.
-
If the effect of the tracks is just to guide it and they apply negligible lateral (X) force, then it doesn't change anything because they skates are probably still free to slide small distances laterally in their channels as the truss deforms. You m…
-
Usually you can. I didn't know there was a limit of 100 elements sharing a node. I just tried with more than 100 beams sharing a node with a shell and it worked. So I'm not sure what the limit really is. What CCX version are you using?
-
Regarding constraints, if the skates are free to roll/slide in any direction on the floor, you should only constrain the vertical (Y) direction to represent them. That leaves rigid body motion in the other 3 degrees of freedom (translation and rotat…
-
To select edges, you can orient the view along the edge, select the nodes which are all together, then switch to select faces mode. Extrusion keeps the extruded elements connected to the original ones and components don't do anything in the solve…
-
Yes, the extruded elements can have different material properties. After extruding, select them, right click one, and Add elements to new component. Here it is with appropriate master and slave surfaces and it solves successfully.
-
Keep in mind that elastic bonded contact moves the slave nodes onto the master faces, so it might severely distort the mesh with the master so far away. Distorted elements cause non-positive Jacobian determinant. Try using the frame face as master a…
-
@3rav OK once I figure out how to compile it and use Github :P
-
Could you send me an example file with the configuration problem? I just tried one with two configurations and the suppressed things were the same as in v17.
-
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…
