Upon further investigation it appears that this problem is associated with the meshing "Size grading" slider. My original post had the slider set at 7 from the bottom. If the slider is increased to 10 from the bottom (most aggressive) then the maxim…

Sergio -- Very nice tutorial (https://we.tl/t-LIeS8U1LIz). Thanks. If your step file isn't confidential, could you also post it so that I could follow step-by-step?
-
Sergio -- From your post of August 11 (tutorial for creating conformal meshes in Salome and exporting to Mecway) -- https://we.tl/t-v0FNRrOzLt I tried to access this but the site said "Transfer expired." Can you post this again (possibly as a more…

Sergio -- I now understand the process to see the the small black balls for the TIE bonded nodes -- 1. Click on a TIE bonded contact surface in the tree. 2. \Edit\Select nodes This shows all of the nodes on the selected surface but not necessaril…
-
Sergio -- For "seeing" the bonded contact, what I found easier is change the visualization to wireframe only (you could even change the model edge color to magenta for even easier visualization), and then select the TIE in the three, and should be h…

Victor -- Works well. In the meantime I did think of an alternate solution (not so elegant can be used for Mecway before v. 16) -- For all GUI models, set "Analysis\Save after solve" to Dummy.liml (or some equally generic name that will be used i…
-
Victor -- I started the GUI and verified that no results were shown under Solution. (This model had previously been analyzed in the GUI. However, I had chosen Solution\Clear prior to running from the command line). I then reran H10a.liml from th…
-
Victor -- For the GUI analysis I just used the time that was shown in the "Details ..." in the bottom left of the CCX Solver popup panel. For the cmd command line analysis, I put a timer (DateTime.exe, attached) just before and just after the cal…

kennethfugate -- By "output window", do you mean the window where the model is displayed? When I right click in this window nothing happens. What Mecway version are you using?
-
Victor -- I tried this but the UI didn't start and I got the following error messages (the first was immediate and the second appeared after several minutes with the first message still open) -- If click Yes on the second message then the first …

Regarding my original post with the weird displacement field around the stud (the last image and its associated discussion; Static_elastic_bonded__1e12_GPa__20a.liml) -- This has been resolved by changing the solver from CCX to Mecway internal (see…
-
Victor -- I reran the model with TIE bonding and looked at WarnNodeMissTiedContact.nam. With a position tolerance of 0.1 mm there were 22 unbonded nodes. These can be seen on the slave surface of the stud (blue dots) -- To visualize the unbonded…

Improve method for changing geometry file location -- If Geometry can't find a geometry file (e.g., a stp file), then the file name of the missing file is displayed in red under Geometry. Right clicking on the missing file's name and then "Wha…
-
Ansys apparently allows this (https://forum.ansys.com/forums/topic/interference-fit-pressure/) unless the legend colors were manually inverted. (The model is for an interference fit.)
-
disla -- That wouldn't be the way the part is located in physical space (then it would be upside down). However, I would use this method if no other easy options.
-
Apply button -- There are two menus where an Apply button would be helpful. This would save the (small) frustration of having to re-access the menu if the initial results weren't as expected. * \Solution\Deformed view settings * \Tools\Options…

I wasn't aware of symlink. This works after a fashion. All links are "live" (concurrent) so any changes made in Mecway_limited are immediately also changed in the online backup. Thus, you can't use the backup to restore user.config to a previous sta…
-
Can the path to Mecway_Limited be specified elsewhere for easier backup? For example, I have my Mecway backup set to E:\Data\Mecway and I would like to put the Mecway_Limited folder there (E:\Data\Mecway\Mecway_Limited).
-
In what file are the contour colors saved so that I can make backups? What else is saved in this file?
-
Duplicating the colors and setting the number of colors to 10 works. Some extra work but that's OK. (I confess that I don't see the advantage to interpolating the colors. As I see it the colors are only a visual representation of the performance. He…
-
Victor -- I'm trying to find colors that convey the FEA info and that look good on the screen, on color printout, and on gray-scale printout. Your suggestion of duplicating the colors works in a way. I tried duplicating the red color in "Custom col…
-
Victor -- "The contact surface of each element is a higher resolution triangulation of element face than what the display shows so it can follow curved deformation that looks like straight half-edges in the deformed view." The image below shows an…
-
disla -- From your "Pull Test Static.liml", could you explain what the boundary conditions in this image mean? I understand NALL but not how "-y" and "x" are used. More questions later.
-
disla -- I tried the following under "CCX\custom step contents" but couldn't get CDIS to display in the solution tree for this static analysis. *END STEP *STEP,PERTURBATION *NODE FILE,GLOBAL=YES U,S,CDIS,CSTR ** U=displacement; S=stress; CDIS=con…

I forgot to upload the model from my most recent comment of June 29 so see the attached.
-
The purpose of my analyses was to evaluate bonded elastic contact with a simple test case. I'm trying to find bonding that will work reliably in most of my analyses (some static but mostly modal) without constant fiddling with parameters. To evaluat…
-
I'd like to see a dialog box for a user-defined view -- * X-angle rotation about X axis * Y-angle rotation about Y axis * Z-angle rotation about Z axis * Zoom factor This would allow exactly the same view to be again invoked which would …
-
disla -- Your "custom step contents" are -- *END STEP *STEP,PERTURBATION *FREQUENCY 5 *NODE FILE,GLOBAL=YES U,S Does the "5" refer to the required number of modes to be extracted? If so, must it agree with the value in "Analysis settings" or does…
-
Victor -- Can you upload the modified model? (Yes, I understand about stress scaling.) Thanks, Don C.
-
Victor -- Your comment of Feb 15 -- "You just need to put any load on it, along with the necessary constraints for a static analysis and that activates stress stiffening which causes elastic bonded contact to work. I've confirmed it with a small so…
