PSD to Time Series OML Utility
Overview: This OML utility generates a time-domain realization of a signal from a PSD given as an input and writes it in a CSV file. It allows for visualization of both PSD and realization of the signal. The input PSD must be stored in a CSV file containing two columns, frequency [Hz] and magnitude. E.g.: 5,1.41E-02…

Irregularities in meshing
I am trying to mesh the circular part of a K joint. I have assigned equal densities in opposite sides. But when we go to the inner region, the density is decreased. I was expecting to have elements in concentric circles which is true at the edges but not in the middle. Other condition is when I have 7 element in one side…

oka wear calculations have poor repeatability
When using the OKA model for GPU-based wear calculations in EDEM, the wear depth results are inconsistent when calculating the same model twice. However, the results are consistent when using the Archard model. This is the first calculation I just roll back the time step to the beginning and click on start the second run.…

EDEM GPU cannot calculate wear volume
I redeveloped the OKA model based on the Archard model released by the community to calculate the wear volume. The program was usable after testing on January 11, but after 10 days it prompted me with the error shown in Figure 1. I carefully checked my code and did not find any problems - the relevant code is in the…
