What a powerful tool to automatically converge the mesh! I'm used to manual mesh convergence studies in proprietary solvers / old school Nastran where you just have to do it over and over again. This has certainly come a long way (have been doing FEA for 15 years)

Ok, that's what you got from PHd holder. Explained the concept behind every single click on that software. Thank you.

That's an amazing lecture! Everything was explained with great proficiency.

What an awesome lecture! Thanks a lot from Wisconsin.

Excellent lesson! Congratulations and thank you so much!

Thank you! I'm glad I could help.

Thanks Dr. Brock Hedegaard

thankyou man

Hi, I'm sorry. I had a question, if it's possible, please guide me. I have a circular geometry (pipe) inside the Ansys Machining software. I want to make a layered mesh, how is it possible?

Hi profesor and thank you for the tutorial; I have a problem that you may know the solution; I want a .ans file to use in autodesk moldflow but I didn't figure out how to export a .ans file from ansys meshing workbench. May you help?

Still helpfull, Thanks :)

i got an error, "A failure occurred inside the mesh refinement module.". what i supposed to do?

hi prof, thank you for your helpful video, do you have any video for stress concentration factor calculation in ansys?

hi

Well explained. Just a small error, the solve doesn't occur at nodes it occurs at a point inside the element which is called integration point and then its extrapolated to the node.

First, thanks for watching! It is a bit more nuanced than just saying everything happens at a node or integration point (I was trying to keep it simple). In the context of elasticity, the typical finite element formulation constructs the solution from nodal displacements that are interpolated over an element using shape functions. Integration points are used with these shape functions for the construction of the stiffness matrix, essentially turning a kind of energy minimization problem over a volume (requiring integration over that volume) into a set of algebraic equations. Once we reduce the problem to a system of equations in the form of Stiffness*Displacement = Force, we solve for the displacements, and these quantities reflect nodal displacements. However, the strains and stresses that we derive from these displacements (because they come from derivatives of displacement which depends on the particular choice of shape function) are NOT nodal values. This means it is correct to say, as you have done, that the stress and strain solutions are evaluated at the integration points and then extrapolated to the nodes, but at the same time the displacements themselves are nodal quantities that are interpolated throughout the element.

this was super helpful! thank you! but i still haven't solved my problem ahhahaha

Well, I'm glad it helped in some way, even if I didn't answer your question. Good luck with your modeling!
