Static structural analysis for rotating wheel

Hi,
here are mesh and command files:

www.dropbox.com/s/kyn5x6a5shjxs8a/rot6_1.comm?dl=0
Just make a new case in aster using this mesh and comm file.

Thank you claws!

simulation goes well with mesh ~250000 elements, but if it is ~500000 than it stops with lack of memory error.
Could you please specify where exactly in Salome I can increase memory (I couldn`t find it)?

As I understand, another possibility to reduce memory usage - to make circular symmetry in such rotational simulation?!
Is there kind of tutorial or example or any help how to make circular symmetry?

Regards.

Can someone please help me with this:

1. How to set circular symmetry in static structural simulation of rotation (to reduce memory usage)?
2. How increase memory usage in Salome?

Regards.

Hello,

for cyclic symmetry in statics you can use something like this for 22.5° cyclic symmetry example (you have to be sure about the angles so better read the documentation of AFFE_CHAR_MECA) :
Changing the memory in salome should be trivial, but I personally don't use SalomeMeca to setup my cases. I remember there should be a very specific setting like "Memory??" in the case setup where you define your command file and the mesh.

Thank you,

could you please help me to understand what does the following error mean?

I am trying to simulate 1/8 of wheel ie 45 deg section where one side of section is set as MASTER face
and another is SLAVE.

Regards.

Hello,
it means that aster doesn't find any mesh elements for projection.
Probably the rotation has the wrong orientation, the rotation angle counts from the slave towards the master. Didi you try with -45?

Best regards,
Richard
