Sorry I forgot to comment I'm using MECWAY 9 and ccx_2.14_MT.exe.

Hello Sergio, Cyclic symmetry seems not allowed in Mecway with ccx. It turns red. The inp file generated by Mecway does not contain CYCLIC SYMMETRY card. If I import the previously "save as inp file" CYCLIC SYMMETRY seems that has disappeared. ¿Am…

Thanks both.

Hello Victor and Guillermo, I have been following your interesting post. I have only been able to force rotation by beam elements or as a displacement imposed on elements at the same distance from a certain origin. Each one has their disadvantages…
-
You could try choosing all rim elements and apply an axis change of this kind (see picture) To open this dialog box ,put cursor on top of the elements , right button and element properties menu

I have found two issues. As far as I know Iges is a surface oriented objects format. No volume will be meshed with an iges file because there is no solid “below the surface”. I have inspected your step file. One of the holes , the one in the posi…

Could you attach the step file if it is not confidential or similar.?

I know it is not strictly related to Mecway operativity, but you have solutions to forget or at least minimize the effects of temperature in the bolting process by means of Flange Bolt Disc Springs (check Chesterton 500 for reference). If your main …

Wow, what a nice challenge. ¿Is the sight glass water tight? ¿I mean, will you pressurize one side of the viewport or is the gasket just to avoid glass to be directly in contact with the braze? If that’s the case. ¿Have you consider to use the gask…

For some reason I’m not able to obtain any result when force is applied to faces. Directly asking to solve from your *.liml file do not provide any kind of solution. ¿It is the same for someone else?

You are welcome. Lifting devices are those kind of things in which safety of people are closely involved. If a chair or skateboard is broken people will probably laugh. 3 Tn machine falling is another thing. Do not hesitate to let us know your res…
-
Hi, UGMENTALCASE. Regarding the design of lifting devices there are some important considerations you should keep in mind. -Dynamic forces can double or triple the real weight you are lifting so use a minimum-minimum safety factor of 2 times your…

Just in case, make sure you are not executing Mecway with the integrated graphics HD Intel® 530.

1-Generate the mesh with custom parameters, gmsh or netgen. 2-Mesh tools/ Automesh 3D. 3-Generate the mesh with custom parameters, gmsh or netgen again. Two meshes are overlaped. The one coming from automesh is not reset.
-
Seems there is an issue with the scale factor of the mesh generated by GMSH. I have tested custom commands with v3.0.7 (latest automatic) and it works apart from this. Mesh.Format = 1; set manually in custom parameters I suppose it is some kind of …
-
I agree with you that Mesh.Format = 1 should remain. As Andrea anticipated Gmsh is preparing a new version (v4) that has been announced as a big improvement.(GMSH Hex generator library will be included) Hope Mecway can take advantage of this new fea…

It is showing the nearest time step that exists in the solution. Thanks
-
MECWAY 9 New feature: “Button to import Gmsh commands from a file”. ¿Is it possible to remove any additional lines to the custom settings coming from the default Mecway configuration? Some of them override custom parameters. I have attached a pdf …

Nice pictures Steve. ¿Are you using bolts or rodbar? I suppose you are neglecting the threads in both the bolt and mount adapter ¿isn't it?. ¿Is it a common practice when modelling studs or bolts? It looks to me like it is a point of important st…
-
Thanks to all for the hints.
-
Thanks Andrea, Victor, I'm using method 1) Response spectrum (acceleration Vs period). Codes provide analytical formulas to compute equivalent static horizontal force. No dynamic analysis is done. I'm now prety much convinced that running 3D dinami…
-
Thanks Victor. I can't find gravity loads. Do you mean to impose “forces”. By other hand, Seismic actions are mainly horizontal effects and gravity is a vertical component. I suspect it is a complicated problem to solve with FEM. In my case I shoul…
-
DaveStupple , you are Right. Loads and Constrains table is reading temperature values in K when should be Cº. It is clearly seen for time step t0 of solution
-
Load your file, change to ccx solver and go back to internal. Suddenly I get an error on the menu for the Rayleight BC (Red). When asking what's wrong I get the attached picture.BC must be applied to whole model and it is not. Once applied to the w…
-
Just comment that old multithreading limitation of stiffness matrix assembly in ccx (CCX_NPROC_STIFFNESS=1) now works with all my 8 threads for me. If anyone still have the system variable set to =1, I suggest to try all available threads.

Those red points have disappear when applying force distributed across the upper surface. Thanks all for the guidance
