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…
-
Try Stress in element coordinates.
-
it would be nice to have harmonic analysis ¿Isn't CalculiX manual v2.20 7.117 *STEADY STATE DYNAMICS that?.? If this is what you are requesting, maybe it is possible with custom cards. First line: • *STEADY STATE DYNAMICS • enter any of the param…

I think you need to switch to 3D

Hi Dculp, Prop_design Here there is an example with a beam in Dynamic 2D. Dynamic also needs a gravity load to convert the mass into an inertial load. I have found something that doesn’t seem to work but this is not my area and maybe I have set up …
-
In dynamic analysis there are inertial forces. I would say the beam needs density too.
