The strength assessment performed by the software LIMIT incorporates a static and fatigue module to evaluate your structure. Base material as well as weld analysis can be accomplished using the commercial finite element code ABAQUS (Dassault Systèmes®).
Required import files for LIMIT
To allow a fatigue assessment of your structure using Abaqus, you have to have the .inp to access the finite element model and the .odb with all relevant result data.
Importing the .inp-file into LIMIT-CAE
- Abaqus (.inp; must be a ‚NoPartsInput‘!)
- Activate ‚do not use parts and assemblies in input files’ in the Abaqus CAE Model manager/Edit Model Attributes

Following elements can be analyzed
Solids (stress gradients are only calculated for C3D):
- C3D4 (lin. Tet-elements) (not suitable for stress assessment)
- C3D6 (lin. Wedge-elements) (less suitable for stress assessment)
- C3D8 (lin. Hex-elements) (less suitable for stress assessment)
- C3D10 (quad. Tet-elements) => stress gradient available
- C3D15 (quadr. Hex-elements) => stress gradient available
- C3D20 (quadr. Hex-elements) => stress gradient available
