Hi , Energy variation or final temperature is the simplest check I can think about. I have an adiabatic system that seems to lose energy through faces in which Heat Flux has been set to 0. I was looking to find some variation in the internal energ…

¿Is ENER or ELSE the right variables to extract the Internal energy of a hot material? ¿Do I have to compute manually according to the instructions given in this post or has something change since August 2020.? It doesn't seem to give any result to…

Some fun,

Not sure if you are aware of this feature.?¿? Sometimes it's easier to group on the parent geometry than selecting on the mesh. You can select faces based on the Step geometry. Like in the picture. All the elements on that specific face will be link…

HI @Philipps ¿Could you share the exact solution for this model or provide the reference to locate it please?. I'm very interested in checking the solution. Thanks in advance

Hi, -I have also found some small jumps on areas where the mesh was irregular, or density changed. Not sure why. I' doing more test. For a uniform mesh and after refinement that difference almost disappear except close to the lib of the shell. -Re…

I have seen your file is called validation. I'm curious. ¿Which is the expected value?. Seems very sentitive to the BC.

Yep, MECWAY typically offers some workarounds. Just be careful to check you have don't duplicate elements or the stiffness would not be balanced. @Victor. Maybe this could be addressed. It happens when multiple rotation +copy are applied to b…

Hi JRP, Revolve/Extrude is reserved to increase the dimension of the object. You can use multiple rotations with the copy box active. (Keep pressing the button). There are two things you need to be careful when doing this. -The axis of beams ro…

i scaled down the developed mesh ¿Are you sure your selected all the nodes and not surfaces or maybe only the visible surface nodes? You can go to Edit--> Select all (Be sure you are in the nodes selection option.

Thanks Victor, I will try to remember the T Rule .

There has been a lot of discussion about coupling and each one has its own recipes to set it up. And not always work. This are some personal advice. -Move the model so the REF node occupy the (0,0,0) coordinates (same as the ROT Node) and nothing…

Thank you, This could be noticeble in thermal analisys too, due to thermal dilation.
-
Thanks Victor, "They use the original element shapes". ¿Could this be improved in some future or is it too expensive computationally? I mean to compute in base of deformed shapes. Thanks
-
@Victor ¿Is that possible? I discarded that option for some days ago according to this post: https://mecway.com/forum/discussion/comment/6572#Comment_6572 ¿Do you mean that if we make the effort to write the custom material properties and Plast…

I understood this could be an error due to the translation of calculation point solution to nodal points.Can anyone advise how to solve this issue? NLMAterial better with solid elements. Check if refinement improves solution. Take a look at this e…

Think in the other way. Mecway doesn't constrain degrees of freedom a priori so you don't need to specify something to behave "free". If you just want the plate not to move just constrain the displacements. I also recommend you follow some of the tu…

Looking with more detail the Strain Energy density hot spots I have realized that there was a chance to improve them even more. Agreement between methods is now even better. I like this method very much . Files updated. **! NL Contact +Perturbation…

Thank you very much Victor.

Hi Victor, I think it would be interesting to have a button that opens the temporary folder where the .frd .dat,... are generated. They are files that contain relevant information and it is a long path and that changes in each analisys.
-
Hi dculp, I have found the rod exact modes formula for the free-free BC. I have run all the 6 tests comparing 1st and 2nd bending and 1st torsional modes and biggest error is 0.04%. You can find the exact solution and test details at : https://w…

Hi Victor, The attached file ,originally posted in the Prepomax forum by Agazzotti , is imported in MECWAY as a unique part. (Prepomax keep it separated as four parts). Keeping the different parts separated allows to assign easily different meshing…
-
It works perfectly fine for me. Seems a hardware/drivers/permissions problem. Probably Victor has some other ideas. I can only suggest you reinstall MECWAY as administrator. NOTE: ¿Did you deactivate the license on your laptop before using the ne…

"Mecway closes during solving stage with no error message." ¿Do you mean the program close, or the solver process stops and exits without solution? ¿Could you share that simple model that is failing with the internal as it is? I understand it onl…

-I would check if Mecway has read / write permission on your workstation. -Play with the temp directory so you are sure Mecway can write there. -¿have you been able to solve simple models?. I mean, ?what happens if you make your laminate just a…

You also have many examples of laminates in the forum with files attached that do not "Crash". Look at this for example: https://mecway.com/forum/discussion/354/composite-laminates-tutorial

Hi Kuhl, ¿Could you post one the files that "crash"?. Without it, is difficult we can help you. Regarding the number of CPU there are many references in the forum about increasing the performance and set up the number of cores. https://mecway.co…
