Hello, I am trying to model the interaction between bacteria and phages but using certain combinations of parameters (namely the time and amount of phage inoculum) I get instability and the integrator aborts the session. I am using a function 𝔪 (for Monod) with a delay injection (condition_2) and …

Thank you! I have tried the new solvers TRBDF2() , KenCarp4() , or QNDF() but I got the same issue reported in the first figure. I then increased the tolerance with soln = solve( prob, AutoVern7(Rodas5()), callback=delay, abstol=1e-20, reltol=1e-20, tstops=[t_in] ) and I got it through: [CASE_3] S…

You can sample the space to build one.
