Tim, you can make named selections of faces in the geometry, and use it for the bonded contact.
-
The beamdy10.inp example must be run from the command line, don't know if Mecway will import and solve.
-
Hi Victor, sorry for posting this CCX exclusive question here, but maybe (well... sureley) your understanding is far better than mine. As per your recomendation I look in the CCX documentation and set of examples, I took the beamdy10.inp (attached)…
-
Guess that you can leave only the nodes on screen, then make a circular selection to select all the nodes of the cilindrical surface of the hole(s). Then with nodes selected you can switch to select faces mode and the selecetion should be converted …

Víctor , you are right, the STEADY STATE DYNAMIC card looks like the kind of steps that I have in my old solver. Will give a try tomorrow. Thanks!
-
Para aquellos que quieran cambiar la ayuda por defecto de Mecway (para que abra estos archivos en español y no los de inglés), me imagino que reemplazándolos en la carpeta donde esta instalado el programa es suficiente. Saludos!

I have checked the Mecway and CCX documentation and examples, and in fact I didn't find nothing similar (or understood) to what I have done in the past (modal superposition), even if the Mecway interface for Dynamic Response there is a Mode Superpos…
-
I don't understant, when you choose Dynamic step, Mecway doesn't include the custom step data. I have changed to Static 3d and it include the custom data as usual, so maybe is a mistake in Mecway. A walkaround could it be define the test as Static …

Fantástico!!!!

Check it now. I have received the ball example with the node to surface, from the last version from bconvergence
-
Scott, in order to finish the calculus you must edit the step time duration to 1. *dynamic 0.001, 1., 0.000000001 , 0.002 also you must add a card to output result as well: *NODE FILE,GLOBAL=YES U,RF *EL FILE S,E There is no way to prevent Mecwa…
-
In teh CCX set of samples there is a test of a falling ball if you want to try.
-
Yea, I thought the same on impact. Nice solver but looks abandoned. Sad thing.
-
I'm interested alsoin drop test cases, have you ever solved using CCX? Another option would be Impact (that is open source), but is not integrated with Mecway.
-
Mecway documentation:
-
I have checked and found that is possible, you must use first a step with *FREQUENCY card to find and store the Eigen frecuencies, and then a second step with a *MODAL DYNAMIC card to apply the impposed displacement. By the way, you can do it also …
-
I did some similar (if not the same) on another solver, but guess that CCX has implemented the same. What I use to make is first run a modal analysis to find the Eigen frequencies, and then run a second analysis called Modal Superposition, using the…
-
Yes, now I realize that what I was using was the "hardening curve"
-
Guess that the best would be the possibility of select the hidden faces in wireframe view mode as is the case with the nodes
-
Yes, meshing takes a little of time. I have meshed the part in Salome, the bolt with 2D in Roshaz and then extrude in Mecway, and the fixture is also a 2D mesh extruded. For making the set of faces at the bolt shaft I have the same problem, there is…
-
Yes, exactly
-
Scott, I made the same as you (even my part has the bolts aligned in Y). What I have made in order to have the loading section normal to the bolt axis is make a 2d mesh of the bolt and then extrude along the axis, then the shaft elements has faces n…
-
I was able to solve a small assembly using PRE-TENSION card, but somebody knows how to use it if the bolts are not alignated with the coordinate systems? Luckily this part has the bolt aligned, but this is not always the case. Tomorrow I will try w…
-
I will try again with the preload card directly to see if I can make it work. About thermal preload, I'm trying to avoid it.
-
I'm using by the moment a load applied on a set of nodes, this set of nodes has his coordinates system reoriented by means of a TRANSFORM card. I have tried before with the pretension card but can't make it work. I'm working on a production part, so…

Also having a visual representation will help a lot, is a little tricky to figurate the new directions without a visual reference

Hi, in fact I have experience working with non lineal material (plasticity analysis for crash tests), in Abaqus and CCX for alumiium and steel sheet parts. I always introduce the (true) stress vs (logaritmic) strain curve points in the material def…
-
Hi, you can do it by means of the remove kw feature, you need to remove MATERIAL, ELASTIC and DENSITY keywords. Then create a name selection of elements containing al the elements that will have the specific material. Give a meaningful name. Then ad…

I was able to model real parts on Onshape without need to read tutorials or help, something that I cannot said of Freecad. The way of work is very like professional tools like Solidworks or Solidedge.
