AutoFEM Analysis Symmetry of 3D structures | |
For the mechanical problems in the 3D setting (tetrahedral finite elements), a condition of symmetry is the equality to zero of displacements in the direction along a normal line to the symmetry plane. This condition can be set up with the help of the command Fixture in the mode "General".
Setting up a boundary condition for symmetry via the command "Fixture"
The example of using symmetry for the tetrahedral finite-element model. On the left is the initial problem and its reduced form, obtained with taking into account the symmetry, is given on the right
For convenience of setting up the condition of symmetry in mechanical problems, AutoFEM Analysis has a dedicated command “Plane of symmetry”.
