My simulation keeps sending an Error message

I am working on creating an incomprehensible LBM sim on an academic plan which should give me 2000 CPU hours I have used none of these hours so far but every time I try the simulation it says I don’t even have enough hours even though at absolute maximum it should only take around 6 CPU hours. I’ve attempted to lower the maximum time but even at the lowest value it still says I don’t have enough hours. Does anyone have any tips for fixing this?

The LBM solver is not available for academic plans - it requires GPU.h instead of CPU.h to run.
