I have some trouble with symmetry.
I have 1/4th of a symmetry plate which is attacked by gravity. I created a support at the green surface, a Master Surface and a Slave Surface with nodes.
I want to use symmetry, thus I used the *CYCLIC SYMMETRY Card. Unfortunately, it doesn’t work. I get the following error message.
ERROR in cascade: the DOF corresponding to node 1 in direction 1 is detected on the dependent side of a MPC and a SPC.
If I understand it correctly, it is not allowed to have the same points in my Master/Slave and in my support surface because they have different ways to calculate the boundaries. However, if I remove the support the spooles solver read the input and starts.
Here is some part of my file:
*Surface, Name=Master, Type=Node
*Surface, Name=Slave, Type=Node
*TIE,CYCLIC SYMMETRY,POSITION TOLERANCE=1.,NAME=T1
*CYCLIC SYMMETRY MODEL, N=4,NGRAPH=4
Internal_Selection-1_Disp_rot-1, 1, 1, 0
Internal_Selection-1_Disp_rot-1, 2, 2, 0
Internal_Selection-1_Disp_rot-1, 3, 3, 0
Solid_part-1, GRAV, 9810, 0, 0, -1
Is there a way to solve my problem with symmetry? I read something about the *EQUATION card but I haven’t really understood the use of it and how to use it.

I wish you all a nice day!
