Convergence issue with optistruct

Recommended Posts

Hi All

 

I am running small model of study of assembly steel tube (modeled with shell elements) into the Plastic part (modeled with Tetra elements).

 

Its Quasi static Non Linear problem, I have prescribed  displacement to steel tube (via rigid) and defined contact between (Node to shell) Steel and plastic parts (Shell as master,Plastic part as Slave).

 

My model is taking lot of  time to solve and analysis is not completing.

 

I have used below contact cards 

 

$$  CONTACT Data
$$
CONTACT        2       5       2       5    NORM2.0           NO
+            N2S
 

Attached is model i am trying to run.

 

Any help is much appreciated

 

Regards

 

Kash

Hi Bharath,

 

Can you share the .out file?

 

Hi Prakash,

 

I have attached the .out file.

 

The Iterations will keep on running and finally the solver will end with Convergence not achieved message.

 

Is Contact the issue here?
