Whether your work include CONSTRAINED_TIED_NODE_FAILURE?

If Yes, then use "create entity" feature to define  CONSTRAINED_TIED_NODE_FAILURE.

Dear Suman,

 

Perhaps this example might be of help:

 

A sphere impacts a plate at high speed causing failure of the plate. This model can be used to show how

different contacts can behave differently in a rather simple model. Instructions of this are explained in the

header of the input deck.

Hi,

I also encountered this error. All the keywords are fine and no error in the model checking. I think my problem is caused by exporting the model from Hypermesh. Do you export your model via Hypermesh as well? I am trying to fix this same problem. 

I also read somewhere that this Error 20001 line #547 can only be found in the dyna.str file. You will need to activate the CONTROL_STRUCTURED and CONTROL_STRUCTURE_TERM in order to get the dyna.str file.

Good luck on finding the solution, please reply when you do. 

BR,

Dear Suman and Bang,

Have you checked the *PART keyword? Make sure that all parts have materials assigned to them.

Sincerely,

Ameen

Hi Ameen,

Yes, all the Parts had proper section and material cards and no error was found in the model checking. I also have checked the model for consistent units. I think this is not a Keyword issue but the input format itself. 

BR, 

Bang
