GeoXPM output tutorial

@tienlk2004 does a timestep of dt is always of 0.001 s or I can change it based on the critical timestep factor?

@madelestin timestep is dynamic based on material properties. You will see the timestep printed on the output log when running the simulation. Else you can find the log where you save the project in _out folder Run.out file (open with any text editor)

I suggest you read one of the paper in the reference page. The formulation for calculating the timestep together with other equations and parameters for SPH is there

@tienlk2004 hi i would like to ask is there a tutorial to plot the chart of stress vs time? because i cant seem to find it and plot over line results in nothing

@Madelestin “Plot Over Line” won’t work if the particle centers aren’t exactly on the line (which is almost always the case).

Instead, you should use “Select Points On”, then “Plot Over Time” for the stress data of that point.

Another option is to use volume averaging or SPH kernel approximation (via the SPH Line Interpolator filter). These methods are similar to “Plot Over Line,” but instead of sampling only along the line, they expand the sampling volume and perform averaging.
