Good afternoon all! hope everyone had a good thanksgiving!
I have been running simulations using DEMdemo_WheelSlopeSlip.cpp and
DEMdemo_WheelDP.cpp, followed by post-processing in ParaView. However, when
I attempt to visualize all particles in the simulation, ParaView crashes.
My system on our HPC has access to over 700 GB of RAM, and I run ParaView
on the following hardware:
- *VisRTX 0.1.6* using:
- Device 0: Tesla V100-PCIE-16GB (Total: 16.9 GB, Available: 13.0 GB)
- Device 1: Tesla V100-PCIE-16GB (Total: 16.9 GB, Available: 16.2 GB)
For the Wheel Slope Slip simulation, the TableToPoints filter uses about
27.2 GB of RAM. However, when I try the "All Points" visualization option,
ParaView crashes every time. I managed to get it working with the "Uniform
Spatial Distribution (Bounds Based)" option by limiting the sample points
to 1,200,000, which worked fine. That said, I know the simulation contains
far more particles than that, as it uses the GRC files we generated.
Is there an alternative setting or workflow I should consider to visualize
all the points in the simulation without crashing? Any advice on optimizing
memory usage or handling such large datasets in ParaView would be greatly
appreciated.
best,
Liam
