**Applying Boundary Conditions**

Before or after generating the mesh, we can define the boundary condition to the FE model to further process it for the solver.####
**Two types of Approaches in Applying BCs**

- Before generating the mesh →Geometry-based boundary conditions for the model. The free mesh generator creates a node for every boundary condition applied to a location on an edge or a location on a surface. The software automatically modifies geometry-based boundary conditions during part update and adaptive meshing.
- After generating the mesh we can define node- and element-based and most geometry-based boundary conditions.

Applying boundary conditions is a crucial step in Finite Element analysis pre-processing . So the basic understanding of the real world scenario is must and likewise, the parameters like load conditions, constrains ect should be chosen appropriately to reflect the real world condition.
