MPM-Particle-Generator
The generator allows to create numerical MPM models based on the contour lines of the land. It has three main characteristics:
- the construction of the MPM discrete model is based only on raster digital elevation model (DEM) data;
- finite element meshes are not required;
- the heterogeneities are defined by the DEM data of each material;
Compiling
The program can be compiled using GNU make utility. The makefile is inside the /make folder. To create the executable file, go to the folder /make and run:
bash
/make$ make
To delete the executable file and all the object files from the directory, type:
bash
/make$ clean
Examples
There are two examples: A sine wave model and the Daguangbao Landslide model.
The sine-wave example
The file input is located in the example folder:
bash
/examples/example-1-sinewave/sine-wave.dat
To run this model go to folder and run the generator:
bash
$ MPM-Particle-Generator sine-wave.dat
The mpm model of the Sine wave results in:
The Daguangbao Landslide example
The file input is located in the example folder:
bash
/examples/example-2-daguangbao/daguangbao.dat
To run this model go to folder and run the generator:
bash
$ MPM-Particle-Generator daguangbao.dat
The mpm model of the Daguangbao landslide results in:
Daguangbao Landslide including the failure surface
The file input is located in the example folder:
bash
/examples/example-3-daguangbao-failure-surface/daguangbao-failure.dat
To run this model go to folder and run the generator:
bash
$ MPM-Particle-Generator daguangbao-failure.dat
The mpm model of the Daguangbao landslide results in:
Results visualization
After the generator execute the input file a vtu file is created. This file can be loaded in ParaView in order to verify the model.
