In CCX you can use the card NODE PRINT and ask for the RF (reaction forces) on the node (must be a node set). CCX will write reaction forces and reaction moments in a separated text file (extension .dat). Read the CCX documentation about that card.
-
Probably you are applying two different restrains to the same node. Sometimes happens on the simmetry planes. Upload the model and maybe we could understand it quicker and give a better answer.
-
Can you share the .liml files with the associated steps files?
-
The part must be well positioned in the CAD before exporting to Mecway. You could move it in Mecway, but the CAD will be quicker, easy and more accurate than moving/reorienting the mesh.
-
You can hide/unhide components of the assembly in CGX directly, you must open the .frd and .inp files from the command line. Check the CGX documentation or look in the CCX Yahoo list, I remember that this question was answered there.

The part of the calculus that do the loading.

If I had undertood well, you need to model the plate first without interescting the cuboid, and then by means of a static step move it (including contacts) in X direction to the final position to see the stress on the assembly. After the plate is on…

The iterative scaling option doesn't work. Have tested with 2.11 and 2.13.

Hi, I have tested other comercials solvers on the same machine (Intel i7-3632QM @2.2Ghz / 8GB RAM), with the same model/bc, and found that while was unnable to solve with CalculiX, even with half of the resources (cores and memory) the other ones so…

Victor, for CCX and no lineal models, is possible to implement on next version the FRECUENCY option for saving data every x increment?
-
Thanks!
-
Maybe you need to increase the tolerance for the merge (selecting only the near nodes to avoid mix some small elements in other regions).
-
Some glitch on the display maybe then, I have seen some also before, and with partitioned hexa meshes also so could be related.
-
Could it be that there are some nodes not merged still? Have you check it with Open Cracks view?

For removing the rígid body card, just delete the line that says RIGID BODY. Check the thread that I mention before as I had some similar problems.
-
Just make a try blocking DOF 1,2 and 3 on the nodes at the base of the cube (and removing rigid body card). As I understand, now with the rígid body you will have a rotation when the ball impact the cube as there are no rotational restrain (or even …
-
In case of using RIGID BODY you should add a second reference node to be able to block also the rotations DOFs. Check this thread mecway.com/forum/discussion/comment/1247/#Comment_1247

As far as I rememeber we have talked about this sample problem in this forum, look for my post because I have posted the working model.

I'm using a Windows utility (Vtk Post, https://groups.yahoo.com/neo/groups/CALCULIX/files/VtkLazarus1.4.zip) but is not perfect. I have tryed others but all lack of basic features (not all elements are converted, some fields variables are missed...…
-
Is a normal behaviour. What you can do is first select all the nodes as you say, and then change the selector to elements. Or select the elements directly by the components name on the tree.
-
Roland, in my experience with Solidworks or Solidedge, if I model the components in the origin of coordinates, and then create an assembly with the right position, then if I export the parts from the assembly, they will be exported "in assembly posi…
-
Yes, I supposse that. I will add the PEEK material as per the above spec and then fix one side and apply the load on the other by means of a rigid body simulating a plain bearing (or the plain bearing should be in the two ends???). Just to be sure t…
-
Tom, what you can do in Mecway is after meshing, scale the mesh (so, if you have created bc, loads, named selections... it will be keeped). Can you attach directly the .liml file? I will have a little of time to see it during the night.
-
twilliams55, you can export directly as step in Solidworks, and then Mecway should be able to import it with the right size. Anyway if you don't want to recreate the model, you can scale the mesh to the right size in Mecway directly.
-
For the boundary condition you could create a reference node at the center of the face, then link all the nodes of the faces to this reference node by means of the RIGID BODY card (not present in Mecway solver or GUI, so you should change the solver…

For metal springs, normally stresses are very low. Have you turn on geometric no lineal? And what about the stiffness that you have, does match with the predicted value? Regards
-
Sorry if I use the wrong channel or words, was not my intention. I really appreciate your contributions, in fact I'm using your versions since years.

Somebody has seen a warning from the antivirus? In my case Windows defender says that the file is infected with Trojan:Win32/Azden.A!cl Regards

Is called bonded contact

For this kind of geometries If they are perfectly modeled in the cad, then it should be able to merge it on the same cad program. As you say, sometimes you need to force the intersection to make the fusion to work. If you cannot do it in the cad, su…
