The given tutorial approch from ansys ALH showcase capacity fading problem can be solved using NTGK approach. Which is true, but it gives out put results as Voltage Vs Time. If I wanted results in terms of voltage Vs cycle (charge discharge). What should I do, and what will be the modeling approach?

Hi, in Fluent you can only plot against flow-time or time-step for transient cases. You can however, write out Report Definitions to a file and then plot the values in Excel for comparison. Please look at 38.2. Monitoring and Reporting Solution Data (ansys.com) on how to "Report File"

Thanks, So evntually you mean in ansys when we do capacity fade test, there is no such method to directly plot Ah (Capacity fade) Vs number of testing cycle. Like Ah Vs Cycle.
(Source: Multiscale investigation of discharge rate dependence of capacity fade for lithium-ion battery - ScienceDirect)
However, the results we generate in ansys based on feed HPPC test data are transient and only solve for certain discharge rate (discharge cycle based on given C-rate until stop condition UDS is reached)
Question: How I can get such results, and simulate a parametric investigation of capacity fade Vs number of cycle.
