Hi Mike, I have read that your formula refers to what EC2 calls fctm and it’s a mean value for tensile strength. fctm [MPa] = 0.30⋅fck^2/3 and it is valid for a range of concrete class ≤ C50/60 fctm [MPa] = 2.12⋅ln[1+(fcm / 10 MPa)] for concrete c…

Hi, I ‘m working to get that concrete beam reference file for MECWAY/CCX. Segio suggestion is too intimidating for me to start with concrete, so I’m starting with a simpler example. It is based on an EC2 calculation of a simply_supported T cross se…

Great, Are you using the old portable version of MFRONT or the new published?

Oficial ccx_dynamic.exe ver 2.21 as your ccx solver. http://www.dhondt.de/calculix_2.21_4win.zip @Sergio Most of the available material models I have tested doesn't or provide nonsense results. Each material behavior .mfront need the user revisio…

Well, That's some progress. Could you push on the Details button and post to see what’s the problem.?
-
Have you set up ccx_dynamic.exe ver 2.21 as your ccx solver.? It should look like this.
-
Hi Fernando, Rafal.brzegowy will try to compile a new portable version by the end of this week. Let's see if that helps. Mean time you could try the old portable one. It works for me, at least for the most basic material models. Just put all those…
-
Strange it worked before. This is like a press and typically works better solved imposing displacement.
-
How did you install the Library.? What's the error message?
-
Hi Fernando, Do you have some realistic parameters for a standard concrete.? Let's Say HM-25 I can't find information about : **• Dilation angle ψ in degrees and the relationsheep between **• Cohesion yield stress and its Equivalent plastic st…

Now I have remembered I already made a test example with Mohr Coulomb but it is related to Soil Stability. It is a copy paste based on a You tube video and I did not found too much application to my working area so I didn't go more in deep.
-
I'm not civil engineer and don't have experience with concrete, but if anyone else is up for it, I'm in. I can try to apply this Mohr Coulomb to my previous file as I know is converging fast. Later we could try; 1.2. Reinforced Concrete Beam or …

Be careful if you are using: PASTIX_MIXED_PRECISION = 1 It can speed up the analysis but there has been reported some issues.
-
I assume that this option allows using multiple processors For running multprocessor, create new Windows System Variables with settings: OMP_NUM_THREADS=6 CCX_NPROC_STIFFNESS=6 Using more than 6-8 proc for most models will not reduce run time f…

Hi Fernando and welcome, Ccx manual says that for those models “In essence, a one-dimensional Hooke-type relationship is established between the principal stresses and principal strains.” So, the Only tension and Only compression materials models i…
-
By other hand. If you still do not have clear the material model for the rope I would do the tests on a much simple and smaller model. Without rotations. Tensile test.

"Project nodes into cylinder tool is way above my league" It's a Mecway meshing tool (Project onto surface). The idea is to prepare both surface's nodes accurately following a desired shape. You have available a cylinder similar with your scenari…
-
First is to make the contact work. Contact problems between curved surfaces require a good initial node position. I would recommend you to start with finer mesh on the belt and use the project nodes into cylinder tool to adjust the positions to a c…
-
Hi Fatigue_Pro. Cool. May I ask you something? I have seen your webpage and results comparison between ccx and Mecway Internal. I have never seen the first eigenfrequency to be higher than the second. Is that possible.? By the way, Merry Christma…

end release beams (Internal solver only) https://mecway.com/forum/discussion/comment/5532#Comment_5532 NOTE: You need to Show Element Surface to apply it.
-
Tanks Victor, Not sure how you did that, but I had a demonic file with some Rigid elements linked like a chain that now is converging. ¿?¿ Mecway is more robust every day. Tanks also for the edge detection on shells.
-
Mecway also allows to extrude points into beams. That could be usefull to you.
-
Maybe related with this issue. Same Model but one is set up in mmgs and the other in MKs. frd result for MKS is 7 times bigger. Another important difference is that MKS triggers mass scaling while mmgs not. I know this is a ccx bug not Mecway but …
-
¿Why is beta damping not working? I’m slowly understanding better how explicit works. High frequency excitations are controlled through a different parameter on the dynamic card. it's time to give the ball a good kick.
-
Hi Victor, I’m in love with those integrals added to the Solution tree. One can track Position of the center of mass, overall Kinetic and Potential energy balance,... I think we could even compute the probability of failure for brittle materials (W…

Drag a nearby element node to Merge with new Hole Ctr., then run Hole Tool. Oh, I like that. !! Thanks
-
Hi, I have done some test on the new tool features based on a given reference (*) and deviation has end up below 0.17%. (Even better than the Ansys reference) Things found on the test: 1-I can't change the SCL direction. Even switching the poin…

Thank you Victor. Lots of new thinghs.

I think I don't have other option now. Thank you Sergio.
