TCL and contact Error

Recommended Posts

Hi ,

 

Could someone tell me how to remove the errors of Penetration. I already used penetration tools.

 

 ERROR ID :          612

 

Also I created the whole file using TCL script Could someone help me on How to implement contact between pulley and Rope as seen in the figure in it. 

I donot know which command to use to select the top face elements of the pulley.

 

(In the TCL script it in the last line about contacts )

Hi George P Johnson,

 

 

Thank you for your immediate reply. I can see you have defined 2 contacts. 

I have a few queries below:

 

  1. How is the predefined initial stiffness of 5000 and its stiffness factor 0.8 assumed.
  2. Why the use of multiple contacts in the simulation? Isn't type 11 sufficient. 
  3. Also is there anything else i.e modified?

HI,

Sorry, i forgot to change this. This simulation will work without STMIN and STFAC values. As  a trial for the previous run I gave these values. Please remove it and run the analysis.

 

The edge to edge interface was not perfectly working and so Type 7 was also introduced with Type 11. No other changes were made,
