SimFat can evaluate each component based on individual material, surface roughness etc. definitions. Or with a complete different evaluation method.

SimFat was original build based on the FKM guideline approach and still support evaluation based on this. Here the correction factors are automatically calculated based on material selection, surface roughness, notch effect etc. And is easy to verify up against the guideline. (If available to you)

Besides the FKM evaluation method SimFat support the possibility to extend evaluations methods based on actual case need.

Loads can be added to SimFat as single loads from e.g. F(x), F(z). And then interpolated to a summed load range. This make it easy to evaluate different load scinarios without having to re-run the FE models. This require that the loads are within the elastic zone when evaluating with regard to high cycle fatigue (HCF).

With the ASTM E1049 rainflow count method it is easy to convert large load series to a number of cycle bins.

By defining an set of nodes laying on the toe of each weld and choosing correct SN curve etc. SimFat can automatically evaluate the interpolated hot spot effect along the weld line. For now basic implementation of DNV GL RP-203 is being tested.

SimFat support FE data from ANSYS. Here both from Workbench and from the Classic ANSYS APDL language. Both native .rst file support and import through script is supported.

SimFat support native PTC Creo Simulate output files. Here both solid and shell elements and results are supported.

Save/Load project is a simple but efficient way to get back to the last state of the simulation.

With multiaxial loading the fatigue life prediction can be difficult and a time demanding process. Initial implementation of a critical plane method to take in to account this type of loading is under development. Different critical plane methods has its and cons and engineering judgement and experience is needed in the case of non-proportional loading.
