rigid contact with arbitrary surface

[Lesage,Anne Cecile J]

Dear all

 

I have tried the following rigid contact option for an arbitrary 2D surface obstacle and a 3D mesh  in python scripting

It looks quite successful

However it takes a lot of time for me to finish a viscoelastic computation (28h)

How can I speed it up? By reducing the number of Newton iteration for example?

I can read in the documentation that there are three other options

How to they compare in terms of speed and accuracy?

How do they compare to a nonlinear stiffness penalty method between the rigid contact surface considered as master and the 3D solid mesh considered as slave nodes sets?

 

Thank you

Regards

Anne-Cecile
