@@medved259 I'm mainly hoping that as many beginner users as possible will find these tutorials. PrePoMax is very intuitive and easy to use, but the videos can be helpful when starting out in this environment. In a way, my goal is also to promote the good practice of verifying FEA results with analytical calculations. This, unfortunately, is an often overlooked aspect.
How can i revaluate the design without moment ...can you help me out with this...i am working on a project where i have toh find the shear stress and total deformation with the help of moment and then i duplicate this static structure and i have to compare this same result without using moment how can i perform this... kindly help me out
So you have to compare the approach involving moment applied via rigid body with a different approach giving the same results? Analytical calculation would be the best way to verify the correctness of the results when rigid body is used to apply moment. Like I did here. There aren’t many other ways to simulate torsion. It would be good if you could show your model and share some details on the PrePoMax forum.
Theoretically, it could be possible to some extent (using rigid body constraints) but CalculiX is not meant for that and it doesn’t offer proper connection types (like connector elements in Abaqus). There are some open-source codes specifically for MBD simulations such as MBDyn and FreeDyn. Currently, a module for FreeCAD that would support MBDyn is being developed. Check Jose Gabriel Egas Ortuño’s RUclips channel.
I wish you would take a bit more time to explain what the options mean, for example, at min 2:16, I wish you would have explained what rigid and tie constrains do, their differences and when to use them; just to name one example.
I cover them in other tutorials too. Here I only presented one possible application of the rigid body constraint, another one is shown in Tutorial 8, for instance. Tie constraints are introduced in Tutorial 11. But I tend to avoid too long descriptions of the available features (since they are described in the manual that I wrote) and focus on examples of their usage.
Are you serious ? In fact, the developer himself asked me to record some tutorials and he references my channel on his website. It’s an open-source software and any help is appreciated. We also prepare the documentation, translate it, help run the forum and so on. But even commercial software needs tutorials from users because the vendors don’t bother.
Great videos, clear, no nonsense. Much appreciated, sir! Thank you.
Great tutorial, well described in good pace, not too fast, not too slow. Perfect!
Thank you very much for this positive feedback. I’m glad that you enjoyed the video. New tutorials are coming soon :-)
@@FEAnalyst I hope you get solid audience of subscribers, so that your efforts get reasonably monetized.

dear sir, love you from india
my self jigar
your Teaching skill is amazing.
Thank you, I’m glad that you like those tutorials.
Thank you very much!

thanks for this video
Is it possible to perform multi body simulation e.g mechanism in motion

Tutorials should be left to the développer of the software not you or any other.

@@FEAnalyst if the développer him self asked you to do some tutorials then I have nothing to say but thanks
