Submodelling with FEDIS enables quick geometric variations for optimization

Trend analysis on a diesel unit injector component.
The peak stress inside the pump housing occurs on the cut edge of two holes (Image 1 and 2).
The submodel analysis method makes it possible to carry out a trend analysis of the transition radius quickly and easily (Image 3). The peak stress' drop can clearly be seen here.
