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…
-
Sorry I make a stupid mistake and download the 32bits version :-) :-) :-) :-) :-) With the 64 bits works ok, the test suite gives me exactly the same results than with 2.10 This is where the patchs for the Paraview results are: https://ww…
-
Bad news kwip, I downloaded the executable (is only that?) and first run the usual test suite... lots of errors and ccx crash almost for any file. Then I try to solve a model from Mecway GUI and again... error! See the attachments. Guess that is a…
-
I understand the point, have signed several NDA and also working for a company that not allow us to share to much detailed information. About the multiple steps simulations, I like also in that way, having different steps for every load rather tha…
-
Great! Have you compiled also CGX? Have read that both are needed.
-
"Paint select's brush size scales with mouse speed, making it easy to select all the way to sharp edges." I'm really struggling with this new behavieur, is dificult to me to make big selections, now the brush is almost a fine brush only. The si…

Can you attach the liml file?
-
Just to give another option to hexameshing, I have found in this new release 6 (not sure if is a new feature), an option to convert tet4 elements into four hexa8 elements, that is, a mesh of tetras to full hexas. They are not so perfectly shaped as …
-
You're welcome :-)
-
Have found a very easy to solve the meshing inside Mecway itself: 1) Mesh using only surfaces (element size=3mm, lineal elements) and uncheck cuads elements (don't know if is exactly necesary) 2) Check that there is some nodes unconected with View…
-
Some missed screenshots :-)
-
For this part you can import it in Netgen (have tried with netgen 6.1) and using the IGS/STEP Geometry Doctor with the default option will heal the part. After you can export the geometry as stp and import in Mecway this healed file to mesh it. I …
-
Great improvents Victor! I didn't have time to test it all, but see some comments bellow: 1) Great inclusion of CCX, for new users will be easy to adopt it. But, can you add a parameter to select the number of processors to use to solve? Now is fi…
-
For some parts Mecway mesher (Netgen) crashes, but if you use Netgen alone works, othewhise try Step/IGS Doctor on Netgen. A third solution is to use Gmsh... and last is use Salome. Good luck! Anyway if you have the geometry you could try to s…
-
Have you tryied with with a bigger size of elements? First order in place of second? Local refining? For big insane meshes I have noted that Salome is better (even if he is using Netgen also). But again, is necesary such a quantity of elements?
-
The problem is that you are meshing only the outside faces of a solid part. Try to import step and do the mesh with second order tetra elements.
-
Can you share the lml file or some screenshots of it? Look like you are triyng to solve a problem with shell elements and no thicknes was defined. Regards
-
Then guess that will be enough with Mecway/Netgen, 90% or more quads and you need to extrude or use shell elements directly. I prefer in CCX or others to use real hexa elements (by means of extrude) than shells (for sheet metal parts and structural …
