ERROR 3018 - GPU memory allocation on device <device_id> failed with code <allocator_error_code>

Description

A GPU memory allocation failed on the specified device. The device ID and allocator error code are shown in the message. This typically occurs when the GPU does not have sufficient free memory to run the simulation.

Suggestions

This typically occurs when the GPU does not have sufficient free memory to run the simulation. Reducing the mesh size or the number of active modules may lower memory requirements. If multiple simulations are running on the same GPU, consider running them sequentially or on separate devices.
