I can't tell what's wrong. I'm running the python scripts with Spyder through Anaconda Navigator while it seems that you're running in IDLE which I cannot as it simply states that numpy is missing. In spyder however, it seems that the next step aft…

I'm still working on this with Mecway as a preprocessor. I've altered the BESO code so that the initial state can be set based on the components in Mecway, so I can make an initial seed or guess in that way. This however exposes the need for more r…

Sergio, it doesn't work as just selecting the script in Mecway and running it as it gives this error message:
-
Sergio, it could be possible but as I have no experience in running user scripts in Mecway and this is also my first serious encounter with Python, I have not yet attempted to do so. If anyone else has the courage to try, then it'd be cool.

I found a setting in the beso_config.py script that exports the solver .inp instead of just the mesh. Thus, the loads, displacements and materials are imported and ready to run. The loads and boundary conditions are however applied to the nodes indi…
-
In the result files, they do not include *ELSETs or *SURFACEs but the node and element numbers appear to be the same as in the original .inp file. Edit: the beso script can be made to export nodal loads and constraints. More details in the next comm…

Hi there Just an update: It works. I set up an analysis in Mecway to be run with Calculix, run the analysis, click "details", then the .inp file button which opens a .txt file which I then save as .inp. Then in the beso python script, which I open w…

Interesting, I'll have to give it a go. Drawing the 3D model will be easy as I'm using Solidworks for all of my CAD work now and are used to exporting STEP files to analyze in Mecway.
-
Nice to hear that it works. Could you clarify what you mean by running it directly on Calculix? I have only ever used Calculix with FreeCAD or Mecway as a user interface and are interested in if this could enable topology optimization using Mecway.

Great to have a .bat file posted. By reading how other people use them to automate tasks it seems to be something I need but I just never knew what a .bat file should be like.

It would be a time saver to be able to automatically generate pairs of named selections for pairs of faces on different parts that was closer than some specified tolerance. It would make it so much faster to apply contacts after having imported a bu…

I just had something similar with simulating a rubber/steel bushing used in automotive suspension. When position tolerance for tie was set to 0, there would be parts which was not connected but when the position tolerance was set to 1mm, then it bo…

So now I got a new workstation and Damn it is fast! CPU: AMD Ryzen 9 5900X 12-core processor 3,7 GHz. RAM: 64 GB Mecway 15, calculix 2.19, ccx_static.exe. Running PaStiX. The same environment variables as my comment above. Runtime with 1 CPU co…

@Sergio I did export some surfaces at the faces because they only bent one way and some surfaces at the mid-plane because they bent both ways or had contacts from both sides and I thought that that would make it easier to make the contacts as the su…

What I'd really like is a continuum shell element like ANSYS has SOLSH190, ABAQUS has SC8R or possibly the "layerwise kinematic method" by J. N. Reddy. It would really be cool for sheet metal or composites analysis but with the difficulties of shell…

@disla 7. These factors are not 1 since they are what is describing the relationship between the stresses and the force, width and module so in some sense they are describing the (assumptions of) geometry and the load direction. It is how the stres…
-
@disla No problems, I'm happy to discuss with peers. Sorry if I'm dragging it too far away from the main subject of constraining movement but I just got excited when I saw a post on the subject of modeling gears. 1. Maximum bending stress and max…
-
I'm also analyzing gears but a bit differently than what you have shown since I'm doing it for designing purposes and are doing it at only two orientations per pair. I'm doing it in 3D because my gears are not completely uniform in cross-section, s…
-
@protontim I've also had issues with meshing gears exported as step files from solidworks where the solution was to check "split periodic faces". I haven't figured out what caused the issue as some gears had issues while others hadn't even though th…

@Victor The "relative to previous" option when placing individual nodes by coordinates has dissappeared in the beta 3 version of mecway 15. Is this intentional or a bug?
-
@Victor, Fine about the solver, I'll just copy files like I did with version 14. If distributed node-surface coupling gives the wrong results, then of course we shouldn't use that but it's just nicer to not have to calculate the magnitude of the m…

Congratulations on the new release. Could you elaborate a bit on the "CCX updated to 2.19 with source code that includes all required MKL files" part? It is still the Spooles solver that's inkluded as far as I can tell, as it is what runs when I r…

CPU: Intel i7 4700MQ @ 2.4 GHz RAM: 2x8GB DDR3L SSD harddisk. Spooles solver: 8min 1s PaStiX solver, OMP_NUM_THREADS=1: 2min 22s PaStiX solver, OMP_NUM_THREADS=2: 2min 17s PaStiX solver, OMP_NUM_THREADS=3: 1min 54s PaStiX solver, OMP_NUM_THREADS=4…

Hi there How many things in the Intel oneAPI base toolkit is required? For example, the Intel Distribution for Python takes up a lot of space so i'd prefer to only install what is nessecary for this to work. Also, the files "mkl_core.1.dll" did n…
