FEM 1.5 CalculiX
FEM 1.5 CalculiX – online finite element analysis
With this tool you can analyse 3D parts from STEP files and receive a clear result report with the key values.
What is FEM 1.5 CalculiX used for?
An FEM calculation (finite element method) lets you assess stresses, deformations and loads on parts already during design. Weak points can be identified early and designs can be optimised before manufacturing.
Typical applications:
- Strength calculation of machine parts
- Stress and deformation analysis
- Optimisation of designs
- Checking parts before manufacturing
- Comparison of different design variants
How does the FEM calculation work?
- Upload a STEP file
- Define material and loads
- Start the FEM calculation
- Evaluate stresses and deformations
- Download the result report
Boundary conditions in the 3D model
After the STEP upload you can select the support face and the loaded face directly in the 3D model. The support is fully fixed; the entered total force is distributed over the selected face. If no valid selection is available, the tool automatically uses faces near Zmin and Zmax as a fallback. These boundary conditions are intended for a quick check and do not replace an engineered support layout.
Which results are reported?
- von Mises stresses
- deformations
- displacements
- safety margins
- graphical result plots
Current limitations
- Large or finely meshed models need more computation time
- Current maximum file size is 50 MB per STEP file
- Results should be reviewed by a specialist before critical manufacturing decisions
