WHERE I AM WRONG?

[Alan]

Dear Professor:

  I want to do a test about Implicit and Explicit. The model is that a small square hits a big square. I can run this model successfully with Implicit method, but when I run this model with Explict, the .exe always exits abnormally and the output show the *ERROR* ENDCLR: End of file encountered in TINPUT Unit Number =  15, I don't know where I am wrong? It disturbs me a lot. Could you help me find where I am wrong and how to correct it? Looking forward to your replay.

Best

[Prof. R.L. Taylor]

You have a "1" on the perspective which is causing program to request data.

I do not thing we include any capability to do "explicit" contact.
