LOADS, BOUNDARY CONDITIONS AND SOLUTION TOOLS
Boundary conditions
Boundary conditions can be defined in the solid model as well as in the FEM model.
Load Definition:
- DOF Constraints.
- Concentrated Loads.
- Surface Loads: normal and tangential.
- Body Loads: temperature, heat generation…
- Inertia Loads: rotations, accelerations…
- Utility to calculate the weight of the structure (New).
- Other: see CivilFEM specialized modules.
Soil Mechanics
Active Earth Pressure (using Coulomb theory) and generation on beams,
shells and solids.

Solution methods (Solvers) (FEM features)
Iterative
- Preconditioned conjugate gradient (PCG).
- Jacobi conjugate gradient (JCG).
- Incomplete Cholesky conjugate gradient (ICCG).
Direct
- Sparse matrix.
- Frontal (wavefront).
Parallel Performance for ANSYS (add-on product).
- Algebraic Multigrid (AMG) (shared memory).
- Distributed Domain Solver (DDS) (distributed as well as shared memory).
Eigensolver
- Block Lanczos.
- Subspace.
- Reduced.
- QR-Damped (damped eigenvalues).
