FluidX3D v3.0 (larger CPU/iGPU simulations)

A little gift to you all: FluidX3D v3.0 enables 31% larger grid resolution when running on CPUs or iGPUs!

Improvements

• reduced memory footprint on CPUs and iGPU from 72 to 55 Bytes/cell (fused OpenCL host+device buffers for rho/u/flags), allowing 31% higher resolution in the same RAM capacity
• faster hardware-supported and faster fallback emulation atomic floating-point addition for PARTICLES extension
• hardened calculate_f_eq() against bad user input for D2Q9

Bug fixes

• fixed velocity voxelization for overlapping geometry with different velocity
• fixed Remaining Time printout during paused simulation
• fixed CPU/GPU memory printout for CPU/iGPU simulations
• fixed bug that default_filename() would fail if there was a . in the file path

Have fun with the software!
