Every time I start loading a lammps dump file of more than 4GB in windows, VMD crashes. Are there any certain modifications I need to make?
Hey There, The most probable reason is that your machine memory (RAM) < what is required by VMD for visualizing the dump file. VMD uses 12 bytes of memory /atom /frame, so you can calculate the memory required by the formula 12*Number of atoms*Number of frames.
Solutions:
1. Load a subset of your dump file, either by limiting the start/end frame indices or by setting a frame stride greater than 1 when loading the trajectory.
2. Expand your workstation specs.
I hope this helps.
Thanks @Nityanshu for your response. But the ram of my system is 24 Gb. The details of the dump file are like: 2000 atoms and 15,000 frames.
The file is readable by vmd in ubuntu but not in windows on same machine.
On windows if you are working with files with size greater than 4gb, make sure you have 64 bit version of the software. For files having size less than 4gb, 32 bit will work perfectly.
