Hello Jose, nAs Rob mentioned, yes, white space can be a cause for the NaN and INF errors. However, also the error can be caused by the discharge data format being used and the options used for the parameter estimation tool. The U and Y data reported in the Fluent console look inconsistent and wrong - e.g. U has values of 6 and 9 (these should less than 4.2) and Y values change from 15-16 to 2.nSome suggestions:ninclude some more points to the discharge test data nremove data at 0 seconds and initial discontinuous time period (i.e. during which the voltage drops significantly)nconsider using lower DoD levelsnconsider using the latest 2020R1 release as the robustness is improved and there is built in functionality to diagnose parameter estimation tool issuesn
