Static structural analysis for rotating wheel

Where should the program get the Wöhler curve from??

Of course you have to define the S-N curve first within the material you USE for the CALC_FATIGUE.
Please check the documentation, it's mentioned clearly.

Hello,
thank you for help and patience!

now material and S-N curve are set correctly.
simulation finished with status "Alarm" - not sure what does it mean, but regular .rmed file is generated normally:

In [U4.83.02] for fatigue calculation I found the following possibilities:
/ 'DOMA_ELNO_SIGM' ,
/ 'DOMA_ELGA_SIGM' ,
/ 'DOMA_ELNO_EPSI' ,
/ 'DOMA_ELGA_EPSI' ,
/ 'DOMA_ELNO_EPME' ,
/ 'DOMA_ELGA_EPME' ,

have chosen the 1st one, but when I look it in ParaView - it is a little bit strange:

how to get (what calculation option select) results in appropriate style, like stress?

ELGA gives the same view (calorific triangles) as ELNO ie is not appropriate...

Hello,
there are at leat 2 problems:
- your fatigue data seems to be expressed in MPa, whereas your models seems to use SI units,e.g. Pa.
- you have a static load which does not change, your fatigue data seems just random since when computing the alternating stress between the time steps you get 0.

Try to use the "ELNO mesh" filter and visualize the field at the nodes, this will look ok.
Nevertheless you should really study the documentation and check if the "fatigue" you are calculating is really meaningful and set up correctly in your case.

Richard
