just keep pushin'

i have been stuck for almost a week now, and it is starting to get a bit frustrating. my simulations work fine in one application, but they are failing miserably now that i have ported them to another application. i am starting to wonder how much longer i should keep trying to solve the problem or at what point should i abandon it. it doesn't help that the compilation and simulations take about 15 minutes to run. so, the struggle continues......
