Dear all experts;<\/p>\n

there is someting confusing me regarding pinned boundary condition.<\/p>\n

In pinned conection displacements will be zero but rotations will be free. In fixed boundary conditions both displacements and rotations are zero.<\/p>\n

In an example like skown below when I use remote displacement as X,Y,Z are zero and Rot X,Y,Z are free I cannot get any solution. I got solver pivot error.<\/p>\n

At point C I am using displacement as X direction free. When I use fixed support at point A I can get solution or If I set Rot X as zero I can get solution.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

For roller Can I use”simply supported” boundary condition or use displacement boundary condition by making one direction free?<\/p>\n

For these boundary conditions both pinned and roller what do you suggest?<\/p>\n

 <\/p>\n

Thank you for your advice and comments.<\/p>\n
