Cannot resolve rest collision: rest direction not set

[Joseph N. Srednicki]

Hello:

 

I receive the warning “cannot resolve rest collision: rest direction not set” when I compile the code listed below.

 

I tried to follow the recommendation in the attached post to avoid the warning:

Is there anything else that I can do to avoid the warning or am I overlooking something?

 

Thanks for any suggestions that you are willing to provide.
