And could be possible to keep load cases inside a configuration? I meant, in NX there is the possibility of with the same mesh/materials, create different load cases (that are solved in one time as the only difference for each load case are the load…

These are the ones that I have setted, all with 8 cores: CCX_NPROC_STIFFNESS NUMBER_OF_PROCESSORS OMP_NUM_THREADS And, using the CXX-MT 64 bits solver provided in the Mecway Beta 3, ccx is using 8 cores for stress calculation, stiffness / …

In my case I use it for hyperelastic and hyperfoam materials only, and always with first grade hexa elements. I'm not sure if wedges has this behavieur coded in CCX.

Hi TPM, in this thread I have posted some comparation between Abaqus and CCX-Mecway. The report is in Spanish, but the figures and results are easy to understand. http://mecway.com/forum/discussion/363/mecway-calculix-vs-abaqus#latest
-
Add a new environment variable with the number of cores that you want to use: CCX_NPROC_STIFFNESS = 8

Is there a way to keep the results outiside the liml file maybe? I have the same problems back in v6 with long runs (no lineal analysis with too much increments and contacts), and yes, open big files can be a nightmare, even worst if is to modify th…

Per component have some kind of logic, as normally one assume that all the volume has the same behaveaur. In the material maybe would be more usefull, imagine the case that one define a blank/template file with all the materials normally used, and t…

Victor, have tried the new colors for the contour plots, and there is one color for "no results". I have selected one color for them, but when I display no lineal results, at the time 0 still the model is showing with transparence. Should it show w…

As far I remember by default unv units are meters, so in NX/I-DEAS we had a way to select the unit before exporting, but Salome doesn't have it. Maybe that's why Victor choose meters as default unit. Regards

Great, tested and now works ok.
-
Update, I open and recalculate both configurations, and then it display different results... great I thought. I delete again the results and rerun and again is showing the same result on both config. Have deleted all again, and compute the first c…
-
This is my first try with configurations, I can't find a way to have two different results, and if I delete one result then the first gets corrupted (or at least the display). Wolud be great to be able to see the different configurations side by s…

Have tested • Gmsh, only adjusting the element size and using local refinements (need to investigate what custom modifiers should I apply still). I felt that is slower than Netgen, but sometimes can produce better meshes, so is a good new feature…
-
Thanks, my liml file is about 500 Mb... will take a little to load on Notepad.
-
Have the same concerns on Mecway, the clasic solutions is use Salome or Roshaz if you want 100% quads. Have tried lot of configurations while exporting from the CAD but none works. Regards
-
After thinking a little guess that will be better to model the pin as a solid and use contact, otherwise RB will artificially restringe the posibility of deformation on the holes.
-
You could define a different RB for each part (guess that you will need four reference nodes in the same point... a little tricky to manage in Mecway), But now you need to link both reference points (those that control displacement, not rotation) in…

The clip is from the Calculix documentation, there you have the full list of CCX cards: http://www.dhondt.de/ccx_2.11.pdf Regards
-
Yes!

Hi, *CONTACT OUTPUT will generate a mixed ASCII binary .frd result file, not supported by Mecway, you must use *CONTACT FILE card in place. Regards
-
Thanks!

Thanks!

Could it be that as the model is IGS you have only a shell mesh? Maybe if you import as STEP Mecway will produce a solidmesh. Or use the Mesh Tools\Automesh 3D on your existent shell mesh. Guess that you must check node conectivity first in the seco…
-
Thanks Andrea for the comments! That's are the things that make's me escape from shell elements while I can, not only in CCX/Mecway but any other solver. For 3D solid modeling guys as me there are severals things to take in mind to don't make mista…

Very often the load directions are aligned with some edge or face of the geometry, so using it directly is easier than compute the vectors. No, I will not put a new node to align a force, is always using existing points, edges or faces.
-
Great! Have tested and works very well, for doing it by means of CCX cards I have to write and think and check the references manual as is not everyday used, but now is so easy. The only thing now is the name, I meant is not doing a support but appl…
-
And what about using TRANSFORM card to apply radial deformations on cilindrical node sets? I found usefull that card in that situation, don´t know how to apply such a condition without TRANSFORM to circular coordinate system the node set Regards!
-
Hi Victor, thanks for the example. Ugly thing is that at postproceesing the tubes are showed as square sections :-(
-
Hi, don't know what exactly means the local h too small, but what can I tell you is that the bending radius and thikness are too small compared with the overall dimention of the part, so for having a good meshing you would need a very small element …
-
Hi Andrea, very interesting information. True is that I don't use almost shell elements, and even less in CCX or Mecway. Why is happening this, is due to the solver or any solver will have the same behaviour? Thanks in advance
