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…
-
Victor -- "Even simpler way but I have no idea why it works. Add the PERTURBATION parameter to the *STEP keyword. Here's an example." Your example works for your shell elements. However, when I tried this on a 3D model (attached), there was no bon…
-
John M -- I understand your method. However, why "Select all nodes, then click the surface icon in the top of the viewport."? Couldn't you first just click the surface icon in the top of the viewport and then Ctrl+A (or "\Edit\Select all") to selec…
-
disla -- Your suggestion (suppressing the bonded contacts) should work fine for static analysis. However, it may be somewhat limited for modal analysis. Suppressing the bonded contacts doesn't actually disable the stud. In addition to extracting th…
-
disla -- Your suggestion (suppressing the bonded contacts) works as desired for analyzing without the effect of the stud. Thanks. For presentation, in the left panel under Solution\Components, I right-click on the stud and then Hide.

Victor -- I ran a Calculix model (77806 nodes) with *FREQUENCY set to 50. The analysis included stress calculations. When a frequency range wasn't specified, the total analysis time was 14:49 minutes of which about 7 minutes were for stress calcu…

Also, Ctrl+mouse and Shift+mouse.
-
Sergio -- Thanks, this works. However, I'm having a problem with box selecting the nodes. First I go to XZ-front view, then box-select just the nodes at the upper left corner. This works fine if the mesh was generated without "Fit midside nodes to…
-
Victor -- I always know the approximate frequency of the mode that I'm interested in because I'm designing to operate at a particular resonant frequency. For example, the nominal operating frequency of my design might be 20 kHz. Then I would only b…
-
Victor -- Highest priority = Frequency response (harmonic) analysis. I understand from emails that this isn't imminent but perhaps others might give some support. Next priority = automatic bonding. Don C.
-
Victor -- Multi-select (Ctrl+mouse and Shift+mouse) would be one of my highest priorities. In particular -- -- Multi-select components to apply the same material. -- Multi-select geometry stp to apply the same meshing parameters. (As an intermedi…
-
prop_design -- Although the Rhino model looks perfectly fine, running \Analyze\Diagnostics\Check gives -- Exploding the model and running the same check shows that the bad surface is, indeed, the small semicircle at the bottom of the hole. (The …
-
prop_design -- I see you have commented here (https://mecway.com/forum/discussion/989/mesh-quality) about having some problems with Mecway's implementation of Netgen. I'll have a look at Netgen's native mesher.
-
prop_design -- Yes, this is one part, not an assembly. The extra lines are there because I need to measure the modal displacements along these lines. (These lines are located where my experimental measurements were made.) Therefore I want the mesh …
-
What Netgen algorithm does Salome use -- is it Mecway's default (don't know what it's algorithm is)? The step file also meshes in gmsh. Thoughts about my other questions?
-
Sergio -- Yes, that would work for this particular model where the stress is high at a point where the two slots intersect. However, this wouldn't work if I need to refine an entire surface rather than at a point, which is often the case.
-
disla -- Acceptable for the time being. I'll see if it's OK for more complex models. Sergio -- Yes, Paraview is good for viewing the results but takes more fiddling (export model from Mecway, solve with Calculix, convert Calculix results to Paravie…
-
Is there any way to numerically specify the location of the cutting plane? In my attached model I have to set the XY (top) view, then move the slider to an estimated position. Then I rotate the model to see if the cutting plane is in the correct p…
-
What is the menu path to the slice tool (or is it an icon)? (I had searched but couldn't find it.)
-
Victor -- Thanks, I understand.
-
Victor -- See the attached Mecway error message. When I run the modal analysis with the CCX solver (inside Mecway) I get the attached result for one mode. This shows that the elastic contact isn't working. Attached is the liml file for modal analy…
-
I have been experimenting somewhat with Paraview. The camera parameters can be set from the "Adjust Camera" dialog box (see image); alternately, the model's orientation can be manually adjusted and the values in the dialog box are simultaneously upd…
-
Actually my original post was incorrect. I don't need the model to rotate about the coordinate axes; I need the view to rotate about the axes. So, following along my original post -- from the default isometric view, rotate the view 37 degrees about …
-
Victor -- Any update on VTK export or alternatives for Paraview? Thanks, Don C.
-
Sergio -- Yahoo groups is no longer active. Do you have another link to VtkLazarus1.4.zip? (Google didn't find anything.) If not, can you upload your copy here? Thanks, Don C.
-
John -- I tried using the *TIE option with with position tolerance = 0 (automatic). However, the gaps still remained. Is the *TIE option relevant to solving my gap problem or perhaps I'm doing something wrong? Where would the *TIE option typically …
-
Victor -- For the elastic option, is there any disadvantage to simply using the highest possible stiffness? (For my test case 1e15 Pa/m works but the solver fails at 1e16.) Is there a way to set the elastic option as the default? My previous FE…
