This introductory tutorial example aims to demonstrate how ParaGeo works at most basic level. You are recommended to undertake the present tutorial example before looking at other examples that cover more specific topics. Specific issues covered in the present example are:

 

•Data format definition in data structures

•How definition of boundary condition works in ParaGeo (Support_data and Global_loads)

•How ParaGeo reads the data and definition of several simulation stages

•Usage of Geometry_set data for a more practical definition of boundary conditions

 

 

Problem description

 

For the present example the geometry, boundary conditions and material properties are kept as simple as possible to facilitate understanding. The geometry will be a square with 1 m long sides with roller boundary conditions at the base and sides and a prescribed compressive displacement at the top. Plane strain conditions are assumed and the material will be modelled with elastic properties. The mesh will consider a single element.
