TCL and contact Error

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 Kartik,

I doubt whether Type 7 will work for this contact. You may have to try with Type 11 contact.

Please go through https://www.youtube.com/watch?v=mLGwVwYSmt4&t=56s&index=4&list=PLQ7KUGFuVz4u5y3SvIEIU07427-gATaG6 which is a webinar on RADIOSS and chapter 4 deals with contacts.

I saw the documentation and the video.

In the user guide it is mentioned it is applicable for 1D mesh image.png.bddd5b5f308b55f991337bab2d71ab95.png

WIth support from the youtube video I have created the contact. But my contact is breaking . The simulation h3d file is attached. could you tell me what the problem is ?

thanking you,

yours sincerely,

kartik

Hi George P Johnson,

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

I have a few queries below:

How is the predefined initial stiffness of 5000 and its stiffness factor 0.8 assumed.
Why the use of multiple contacts in the simulation? Isn't type 11 sufficient.
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,
