Hi

Firstly, I would like to thank for your answer.

 

I tried to analyze the roof crush problem in optistruct, I set up the parameter as following.

The vehicle structure, I defined the contact type as freeze.

For the rigid plane that press the vehicle body, I defined the slide contact.

And also, Analysis type, I used Geo non-linear (Impl static).

 

While I am running the problem, the solver interface shown that they used Optristruct solver,  after that, i think, they changed to RADIOSS solver.

 

 *** ERROR # 4001 ***
 Running RADIOSS starter, 151 ERRORs and 53 WARNINGs have been detected.
 They are listed below.

 STARTER ERROR:
 ERROR ID :          556
 ** ERROR IN INTERFACE TYPE2
 DESCRIPTION :
    -- INTERFACE ID : 5
    -- INTERFACE TITLE : INTER_TYPE2_5
    MASTER NODE ID=42374 IS ALSO SLAVE NODE OF ANOTHER INTERFACE TYPE2

 STARTER ERROR:

The error details are shown as following picture

    Hi @Wisawanart

     

    There are few nodes which are both master and slave. Can you please check and update the same?

     

    If you still face the issue, please share the model file with us.

    Hi Mr. Prakash Pagadala

              I am wondering concerning this analysis type (geo non-linear (impl static)) when I used this type the solver shown they have some contact error as post above.

    That mean, Radioss did not allow to has double contact in one contact group right?

               After this problem, i tried to set this problem also, I analyzed by using non-linear quasi-static type ,then the result did not convert also.

    Do you have some tutorial that related to geo non-linear (impl static) type so I want to follow your recommended tutorial to understand in this problem.

     

    Best regards

    Hi @Wisawanart

     

    I am sorry I didn't understand what you mean by '  Radioss did not allow to has double contact in one contact group right?' 

     

    Have you seen this tutorial using NLGEOM:

    Hi Mr. Prakash Pagadala

    Firstly, thank you for your answer and also sorry for my English comprehension.

    From previous post, I intend to mean, If some nodes are both slave and master, this condition will be incompatible for RADIOSS right?

     

    Best regards

    Maybe not... Self contact will work...

     

    Is it possible to share the model for both NLSTAT and NLGEOM?
