Re: Von Mise stress higher than Max Principal Stress?
Ruben, please run attached model, check the results for von Mises stress and Max Principal stress, and explain how the results fit in your theory?

The Reynolds Equation is used in Lubrication Theory, not to be confused with the Navier-Stokes Equation. https://en.wikipedia.org/wiki/Reynolds_equation...

How about just using beam elements for your sensitivity study?you can export graphs directly to MS ExcelMuch faster to runUsually enough information for "standard beam bending" The beam length is not...

Re: How to constrain long profile?
In many cases beam elements are useful, as you say, only a few elements can replace many shell/solid elements. But in this case I would stay with shell elements. It's an open section, and beam elements...

Hi all,for work I use Creo 3 linked to windchill so, to open a file, I look for it always inside a workspace of the PDM. For our corporate rules, the only CAD files that we manage outside the PDM are...

Re: How to constrain long profile?
Now I change absolute accuracy and shell elements can be made as long profile as I want. So, the length of the profile or shell elements is not the problem. Still I am not sure what is the best...

They are all tests.I have tried with vary time steps, at each time step both on "Auto" that on "User defined". The true is that I still don't know how to do. Now, while I'm writing, I've launched an...

Guilio, I will check my CPU usage. The gap : you don't need it, it is of no use. It slows you up. timestep function vs master steps. I saw that you had 60 master steps after my earlier post. As far as...

Well, that version has solved for me in three (large!) steps - the only odd thing is that the block seems to be moving sideways.You've used a 'planar' constraint on the bottom face of the block; I...
