hi,
I am trying to solve the Lithium ion battery model from the model library (li_battery_1d). I am always getting this error message while solving study1 in it .Please help me on this.
Repeated error test failures. May have reached a singularity.
Time : 3592.798153276032
Last time step is not converged.
Thank you

aha,
I solved it.There are two studies in Li ion 1D model.study1 is using a particular current profile (i_app) as input .Study2 is parametric sweep which uses constant discharge currents with different values (i_app_p) till the battery voltage meets a stop condition. While running study1 the 'electrode current density' variable in 'lithium ion battery menu' should be set to ' i_app ' and when you compute the study2 this variable should be changed to ' i_app_p '.
