Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Comet Interceptor is an ESA mission, which will be launched in 2029 towards an as-yet-undiscovered dynamically new comet. The Dust Impact Sensor and Counter (DISC), developed by our team, will be mounted on board two of the three planned Comet Interceptor spacecraft, aiming to determine the coma dust features of the target comet. DISC’s sensing plate will be exposed to the cometary dust environment and subjected to Hyper-Velocity Impacts (HVI), due to the high flyby speed (10 – 70 km/s). Laboratory facilities do not allow us to test the whole range of impact cases that DISC will undergo during the measurements. To overcome this limitation, we implemented a simulation system with ANSYSTM software and the AUTODYNTM hydrocode, able to reproduce a wide range of dust particle impacts. The simulation process involves a hybrid model, which is discretized with both Smooth Particles Hydrodynamic (SPH) and Finite Element methods (FE) and organized in two connected phases. The results we herein illustrate confirm that the simulation system we implemented allows simulating the DISC operative phase in an efficient, fast, and reliable way.
