Posted by Albert Montolio Aguado at October 29. 2015

Hi everyone,


 I have problems with a DIS_TR element which I called 'hinge'.







I defined the properties of the element this way:










and keep receiving the

following message;

I don't see the mistake in my command file unfortunately.  I think it has to do with the connection between a DIS_TR and a DIS_T.  I attach the file .mess, just in case anyone could help me. I would appreciate any kind of hints.
