Many new users have a general question related to boundary conditions for structural analysis: “I want to apply a force to a surface but I cannot select any surfaces to apply a force on. I can only select nodal load, but cannot see the force boundary condition.”
The following information will help you.
Reason for Basic Boundary conditions:
1.SimScale provides user with functionality to use two types of solvers for Structural analysis.
2.Type ‘Static analysis’ is a basic setup which has Calculix running as a FEA solver. The option of boundary conditions provided are as follows:
3.Type ‘Static analysis - advanced’ is a more advanced which has CodeAster as the backend FEA solver. The option of boundary conditions provided are as follows:
4.Since you chose the analysis type to be ‘Static analysis’, you can only view nodal load.
Therefore, in order to use more variety of boundary conditions, select ‘Static analysis - advanced’ to be the analysis type.
Update [July 12th 2017]
With today release we made some changes to the default analysis types, their naming and visibility. From now on the default static and dynamic analysis types have all available load and constraint options as they are now based on the Code-Aster solver and the previous advanced analysis types. The CalculiX-based analysis types are still available via the solver perspective choosing the Calculix solver. For more details see the release notes.
