How to handle convergence
I am using a simple 2D grid to simulate the growth of hydrates after some gas injection occurs in the system. Ideally I would like to shut down the source (injector) and let the system evolve with the injected gas. Nevertheless, when I set the injection rate to 0 in the `GENER` section, the simulation crashes.
I get the following error. What would be the best way to tackle this. Would I have to use the UPDATE section, or is there something to set in the PARAM section that can help me.
In <SS_Rate_Interpolation>, the time value 1.7356700E+11 is outside the range ( 0.0000000E+00, 1.7356700E+11) At <Tot_NumTimeSteps> = 145 the time exceeds the maximum value in the generation time table at elementA2Q09 (source GIn00) ==> will reduce timestep >>>>>>>> CONVERGENCE FAILURE on time step # 145 with Dt = 3.281375E+00 seconds, following two steps that converged on <NumNRIterations> = 1 ==> STOP EXECUTION AFTER NEXT TIME STEP
