incorrect normal directions

incorrect normal directions

incorrect normal directions

(OP)
Am having error:Nodes have incorrect normal definitions.
am modeling a truss embedded in a solid (beam) using a conctact pair option interaction.

i don;t know how to fix this error.

RE: incorrect normal directions

Can you supply the CAE? its easier to understand the problem then

RE: incorrect normal directions

(OP)
Thnaks for your reply, even smaller mesh did not solve the problem.
Am attaching the CAE file to look at, hope u can find a solution.

RE: incorrect normal directions

Cant' find the CAE

RE: incorrect normal directions

(OP)
I uploaded to engineering.com. under name:UPPB020S-ancho-1.cae.
dont know another way to do so.

RE: incorrect normal directions

(OP)
were you able to download it?

RE: incorrect normal directions

got the CAE, look on it
which model is the most relevant?

RE: incorrect normal directions

(OP)
What do you mean? if you meant what interaction that causes the problem
then it is (int-3/4/5/6) (the interaction of solid faces with middletendon)
however, i also tried to create ons set of all surfaces and define one iteraction but nothing was solved.

Steps i used to check the normalare as follows:
try to run the model/ go to results/ common plots/ trun on Normals/  you can see that the normal vectors are pointed out, however, they should be oriented inside to interact with the middletendon


Thank You,
