			An overlay's simulation model contains many data arrays to do the calculation on the GPUs. When this error occurs the total amount of data arrays needed to do the simulation does not fit in the GPU memory. This error is hardware limited and can only be resolved by creating a smaller dataset. It can be resolved in two ways: First increase the grid cell size (less cells means less memory). The second option is simplification of the simulation by for example using less result types or model option.
