How to export your dump file values to excel or any other program for contour plots

Submitted by wenglee on Tue, 03/29/2016 - 16:42

Hi all,

I'm a new user of liggghts and I'm studying the problem of heat transfer. I was trying to figure out a way to export the liggghts temperature data to an external source to plot a contour plot for surface representation (for example, microsoft excel or matlab). Through the dump files I was able to obtain some values of temperature with respect to position x,y and z as shown in my attached image in this post. However, that is only the 10000th dump file that I obtain through the liggghts simulation and there are total of 800000 dump files in my post folder. It is impossible to open all 800000 dump file at a time and then export the data in the dump file into excel or maybe matlab for graph plotting. Is there any other way to extract the data from the dump files without going through all 800000 dump files created in the post folder?

Thank you in advance.

I really really need some help to solve this.

Hi, I have created the .dump files which has information of position, velocity using DEM simulation and paraview. I want to convert this dump files into an excel files. Can anyone suggest the process regarding of this conversion? I want to use these excel files as a dataframe using python for my further process.
