If you revolve only one element there should be no difference. If I’m not wrong Victor comment that this is what ccx is internally doing when modeling Axysimmetric shells. In this sense, this method could improve the “pure” axisymmetric approach as …

Hi again Andrea, You could get full hex mesh combining the mesh tool Create plate mesh + later Custom refinement of the contact surface. This way you can refine the area of interest preserving the hex mesh. Final extrude if needed.
-
Yes. Pyramids are written as C3D8 for ccx .

Hi JohnM, One variable that often goes unnoticed and I usually forget to set is "Generate solution at XXX time steps". If you are not particularly interested in the nonlinear process evolution but the final result, you can save a lot of disk writin…
-
I forgot to mention Output2D is required if you are modeling with shells as they are expanded. With solids is not needed.
-
You must first select the mode in the solution, then go back to the modeler and use Transfer displacements from solution in the Mesh tools menu. The active mode will be transfered You will be asked to provide a scale factor in the process. It is im…

I have just realized there would be a much easier way to do it. Fix one end of the wire to the pipe and the other fixed in the space. Then rotate the pipe instead or pulling the wire. In any case , work first with the simple model . The set up will…

Start from simple. 1 turn model to understand what is going on here and the physics behind the problem. Maybe you don’t need so many turns. Pay attention to the key role of friction in this problem. Try to converge 1 turn first.

Hi and Happy New year everybody, How is the animated solution constructed when performing frequency or buckling analysis? Unlike static, this type of analysis does not seem to interpolate between the model at rest and the solution. I ask this be…
-
@LHartley , You are absolutely right. It makes no sense to skimp one or two millimeters of thickness on such a small part. You never know where an unforeseen load may come from. I've seen workers on site pulling with a tractel tied to the column t…

I have been discussing about this recently. According to my new spreadsheet could be even less. SHS 65x4 S450. Pcr (Euler)=635KN Ncr ( EC3 )=635 KN Nb,Rd=261 KN (Cold Formed- Curve c ) Nb,Rd=347 KN (Hot Formed- Curve a0) In any case Nc,Ed=3…

Hi JRP, 1-I don't think you need to move the unzipped files to the Mecway folder. Just keep them all together in the same folder and point to the .exe file from the MECWAY menu: Option/CalculiX. 2-Add the unzipped folder with all the ccx file and …

That's the link sorry : https://mecway.com/forum/discussion/1150/1d-beam-bolted-connection I may simply bond the riveted surfaces. That's why I erased the post. Contact with separation do not work in Frequency analysis so you need to bond both sur…

Hi JRP, There is a precompiled version from Rafał Brzegowy with all the required MKL *.dll at: Specifically the File : https://www.tu.kielce.pl/~rokach/instr/misc/ccx_220.7z You can translate the webpage first for detailed instructions but shoul…

-ccx_dynamic.exe = spooles (static), pastix (static), pardiso (dynamic),requires oneAPI MKL library -ccx_static.exe = spooles (static), pastix (static) There is more information at the README_Install file . As you call ccx from inside MECWAY you …

This ones too?

Regarding point 3 ¿did you Extract (Unzip) the ccx folder or just copy paste? You need to unzip. In my case it looks like this: Check those files "cannot stat" thye are where they should

This are the detailed instructions contained in the installation folder of MECWAY. In my case C:\Program Files\Mecway\Mecway17\ccxMecway/ccx/ccx_win64_mkl_pardiso_source_2.19.zip file -Instructions for building the following on Windows: 64 bit …

¿Are you using ver.14 for some specific reason?. There have been some bug fixes on the last versions/years. Last versions have a folder with all the required instruction to compile ccx v2.19 with MKL Pardiso OCC. Regarding your warning it happens b…

I have to right click on Loads & Constraints in the tree and then I get the option to set it. Right. It works that way. Take note of the nodes number first.
-
Look at Loads & Constraints ---> New Constraint equation

¿Are you considering steel as the main material for the truss?. You have a Young Modulus of 200Mpa. ¿Don't you mean 200 GPa.?
-
.
-
Much, much faster. It is instantly noticeable. Thanks once again for the update.
-
I have never use it, but you can mesh just the edge nodes with gmsh. Also you could mesh everything and select only what you need later.
-
Hi NoahKatz, I would say that both , adding beams to an edge and meshing only one face could be solved once the mesh is generated by adding them manually or removing the unnecessary faces, respectively. If you have a typical step file you normally …
-
Yep, -Select all the holes inside surface with the edge detecting tool. -Extrude to the inside direction (normal) to create the solid pipe. Recommended three elements per thickness -Inmediately create a new component. -Hide all but the new componen…

You need to input a value at the Second moment of area in your last file KM_32b_static.
-
I have requeste it in the solution tree directly. Not a formula. Right click on top of Solution--->>New Stress and Strain-->Stress in element coordinates. Appart from that, I don't think the material properties are right in your file KM32a…
