New features in FlexPro8
The Rainflow matrix can now also be calculated in asymmetric form.
You can exclude the residue from the matrix, include a closed hysteresis “a-b-a” in the center of the residue only, or fully include the residue into the matrix.
If you create a Rainflow Count directly for a data set, then FlexPro 8 automatically creates the required Count Matrix analysis object as an intermediate step.
