Transient Non Linear Analysis (Contact)
Hello everyone !
I'm working on 2 dofs models (see below, the picture in right) and I need your help to run Non linear Transient Analysis.
The idea is to compare Newmark scheme implemented in Octave with OptiStruct solver.
I run first Non Linear Transient Simulation in OptiStruct and I found weird results ! For sure I did something wrong in the model.
BCsREM refers to the boundary conditions;
TSetp : TSEP card (DT and N);
DLOAD : Dirac load to disturb the system in order the find x(t) and y(t) oscillations ;
For the contact discretization, I used N2S (The mass CNOM2 to the rigid plate). And I control the contact stiffness via CONTPRM ...
Do you have an example like this ?
Best regards,

Okay. Thanks for your answer /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />
We don't have any example based on your requirement for 2dof.You could refer to below link for nonlinear transient analysis.
Hi Rahul,
Where i can find the model file for this? i want to try this.

Hey
There a good book provided by Altair. Inc. You can find the basic of what you're doing. You can find as well the model described in details ...
Cheers,
I forgot ! for the model you can start from the page 167 /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />
