TIME STEP LESS OR EQUAL ZERO

Hi Sekar,

Does your model have contacts?

can you share the complete out file?

Thank you for your fast reply. 
I'm an absolut beginner in the world of simulations. That's why i am thankful for every help and support!
Attached to this post is the OUT file. 

I haven't created any connections between the layers. I only created a contact interface.

Please let me know if you need any more information.

Okay, 

what type of contact are you using?

can you increase the gap between the components with contact surfaces and check if that helps?

if you are using type 7 contact can you check with a gapmin= 0.1 or up 0.5?

I'm using contact type 7.

Thanks to an other helper (Employee of Altair - not sure if i'm allowed to say the name..) i finally got the solution. My mistake was in the contact interfaces:
Changes were done in the following categories:
* stiffness definition
* Node and segment deletion
* friction penatly formulation

Furthermore the engine file was adjusted: the scale factor and the minimum time step have been decreased.

But thank you Prakash Pagadala for your fast help! 
 

Sekar,

can you share more information on how you change the friction penalty formulation?

Thanks

increase the Gapmin. then it will work.

this is because of negative volume happening due to the contact.
