Mr Patankar & Mr. Sukumar,
I understand you both are at IIT's.

Why IIT's Collaborating With Ansys and Not Code aster. Promote Open Source.

Govt. of India has clearly made mandatory to use Open Source Software at IIT's. Like LInux System is widely used.

decrease SY, keep on decreasing SY...

u will get result.

at the end of test, what results you want.

ORIE_PEAU_3D=_F(GROUP_MA=

for contact faces not define,

not seen your .med file, but remove all sharp corners at contact zone.

Hi,

If you have Downloaded PETSC Solver. Will you please give detail steps for ubuntu 18.04.

PetSc is important for complex studies.

your expansion or contraction due to centrifugal force is directly correlated to your material properties.

i think if torque is applied at pcd on driven gear will solve the problem. code aster at present doesnot allow 0D element with weak spring.

if anyone knows how both 0D +liasione solid and weak spring can be incorporated, please reply.

Mr. Konrayo views are welcome.

i had block DZ =0.0, but DX is Open for movement. if DX=0.0 is also block, Wheel stops Rotation.

solver do converge in AUTO mode. But the Driven Gear shifts in DOF axis. Say DY is 0.0, Gear tries to shifts in DX, DZ. This changes centre distance and thus your torque data goes wrong...Reaction Force goes wrong.
yes it is grabcad file
i am using astk 14.4

ok. see attachment.

we can raise bug to code-aster.
Torque has to be applied to PCD of Gear.
And Code Aster doesnot allow defining 0D Element with Liasione Solid to apply torque , in contact analysis.

Hope, somebody from code aster is reading this.

here i hv attach sepaerate mesh files.
compound them.

"i modify the time step set like this : 0.01;0.02;0.022;0.024;0.026;0.028;0.03;0.04;0.05
run the solver and i obtain the convergence

during temporal window from 0.02 to 0.03 i observe in paravis which the cursor scale of DPL goes to left and after 0.03 to 0.05 goes totally to right."

On above message of MIB.

When i am testing 2 Gears in contact, The Centre Distance Between Gears Shifts. As we fix Single Axis Say DZ,,,but DY,DX are free for movement. if i fix DY & / or DX Gear stops rotation.

To be Realistic Simulation, I have to Apply Torque in Reverse to Rotation to Driven Gear, to Obtain Reaction Load Realistic.
How this can be done. Any Hints.
