Hi, I have some problems with the contact generated between more than 2 beam elements.
I've created about 200 beam elements by lines. and they are located in columns and rows. In order to create the contact between one beam and its neighbouring beams I've created a contact between all this beams saying that the first beam from the first row is the "Conta176" of the second beam from the first row that is its "Targe170" but at the same time it's the "Conta176" of the third beam from the first row that is its "Targe170" and so on.
The program gives me some warnings which I don't know how to solve. The warnings are the following (the first two are repeated more than once:
- The normal of target element 7502 is not consistent with the normal of target element 7517 in real set 1. Please use the ENORM command to correct it.
- The normal of contact element 8587 is not consistent with the normal of contact element 10077 in real set 1. Please use the ENORM command to correct it.
- The self contact pair specified by real constant set 1 also overlaps with another symmetric contact pair (e.g. 1).
Does anyone know how to solve the problem keeping the contact between all the beams as I've specified at the beginning?
