I have been trying to fit ODE based disease transmission model with sero-prevalence data. Since I am fitting with sero-prevalence data, the common practice is to run the model for sufficiently large time interval and get the equilibrium values and compare with the real data. When I was trying to so, if would like run the model approximately more that 10000 time points it throws the error Error: 1 particles reported errors. - 1: too many steps. I thought this is because my model dimension is large enough (dimension:1101) and because of memory issue, I am getting this error. Then I tried with simple SIR model with only 3 dimensions, even then the issue persists. For your reference, I am using R 4.3.1, odin : 1.5.4, odin.dust: 0.3.9, mcstate: 0.9.14, dust: 0.15.1. I wonder if I am missing something trivial here. Any help would be highly appreciated.
