I'm using UNICAL as well, but downloaded from some other forgotted place. I'm attaching it if you want to try. I have associated the .unv extension to the unical.cmd (cmd, not exe) file to automaticly convert the files by double clic on the Windows …

Create the groups of elements in Salome for each material, then export as .unv and convert to .inp using some command line utility available overthere, I made it everyday and works like a charm, Regards

Very good report, mesh is very important for analysis, not only the size but also the shape of the elements, I have seen very weird results (false stress concentrations) due to poor shaped elements. In my humild opinion the solvers (CalculiX, Mecway…

Guess that not possible to get the output from netgen in Mecway. But you can try to mesh directly with netgen standalone application using the geometry doctor to heal it, or use gmsh or Salome.
-
The actual system is good enough, with the first unit selection almost all are then uniform, but still there are some places were this is not happening. There is also some unit (guess that is Nmm or something like that that doesn't give the option t…

"In Mecway, with a 1mm mesh and after mergin nodes at 0.2 distance you get all the elements stitched." No need to make any manual editing, just merging.
-
Will try it! In case of having nodes selections available will easily the plottings tasks. Regards
-
I have tried in the past but guess that there is no automatic way. In such situations I preffer to select nodes (by means of a box selection and playing with the orientation of the model) and after swhitch to edges on the nodes/edges/element selecto…

Have tried with Netgen but it makes a non continuos meshes, even I have used the geometry doctor to heal it. In Salome, just meshing the part using simple parameters looks like if all where conected, but after checking in Mecway with Open Cracks, we…
-
Have you tried with Salome? It has some ways to join the parts and make a continuos meshes. I have made with solids and works, maybe with meshes would work also. If you share the files I could give a try.
-
Could it be that you have removed the step file from the analysis folder? Otherwise upload the step file and we could try to reproduce the error. Regards
-
Dave, I didn´t have any issues with SciTE, the only thing is that for colapsing such a big subsections will freeze the program on my pc. On the other side, Mecway refuses to open directly, that's why I was concerned on how you would be doing it. R…

Great! I will give a look then, sometimes I compute this case of loading and could help to avoid contact. Anyway CCX has improved a lot contact treatment in this last versions.
-
Can you explain how you apply this distribution?
-
Great, I use Roshaz also for quad meshes, that after I import in Mecway to create hexas. Do you know if is possible still to buy a full licence of Roshaz? I have looked for a simple quad meshes unsuccessfuly the last months.
-
How are you working with this huge model? What are you using to preprocess? Regards
-
About units on input files... if we ask for mm why not somebody could ask for inchs? Guess that this could lead to a nightmare for the developer. The new version just arrived, let´s give some breack to the developer. Next week we can start to ask …

Hi Andrea, welcome to the forum! About the step and static card, you can define any quantity of (fixed) increments by means of "Number of time steps" and "Time Step" on the Analysis settings window, then you must define your loads/displacements wi…
-
Have tried to import the model in Mecway with no success, my advice is to start with a small model (few nodes/elements) in order to investigate the boundary conditions with quick runs and after improve the mesh. I would avoid the piramids elements. …
-
Use shell elements in place as in the attached model.
-
Check it
-
Gemada, I don't have experience with concret or compression/traction only materials, but if you arrange the input file or best Mecway file (using custom CCX content) I will give a look and try to make it work. I would preffer to have the part mode…
-
Yeah, but will be a small machine compared with the ones you work. About 40 kN only, but will mine :-)
-
Try exporting as STEP to be allow to mesh directly with solid elements with Mecway.
-
Hi, have you try to model your beam and rebars as a 3D extruded solid? In Salome you could mesh the two components (concrete and several rebars) with coincident nodes at the interface, so you don't have to worry about using TIE or whatever to conect…
-
1) Use a DYNAMIC step card 2) Use ACCELERATION card to apply the movement of the part (don't remember well if the card name is that, check it) 3) Use very very small time increment (so total time will be huge), so use big elements to play until you …
-
You must apply an acceleration (gravity) to the falling part, and you could also apply a initial speed as am initial condition. Look the Calculix 09 channel on youtube, he has uploaded a video of impact simulation this week.
-
Look for the falling ball example in the bConverged CCX version (or this forum itself) Is the mother of all impact simulations on CCX. But don't put too much expectations on results, I don't feel is ready for production.
-
Sometimes I load and unload (but completly) the material (over the yield point) to see how much deformed the part left after the loading. He says that will change the friction between steps, I'm tring to figurate a situation were this must be need…
