Hi Mounir,

 

Do you have a type 2 interface in your model?

 

if yes, please change Spotflag=1.

 

check if there are any initial penetrations, in such case, if you have /DT/NODA/CST in Engine it is recommended to remove it.

 

Please Note: If you are a commercial customer, you can contact your local support for a script that will help you do the same @ http://www.altairhyp...ortProduct.aspx

Hi,

Was the above mentioned problem solved. I am getting the same issue where I can see high values for the nodal time steps in order of 1e 06. I have also used admas option in the input. Only one animation file is getting generated and the getting terminated with time step of 1e 06.

Hi gopal,

 

Is your added mass supprted via Rbody?

 

How about inertia values?
