Tutorials

The following tutorials are designed for new FEAP users to gain a deeper understanding of some important capabilities/features of FEAP.

FEAP Basics

Nodal Stresses

FEAP can compute projections of Gauss point stresses to Nodal Stresses.

Operator Splitting

FEAP allows one to solve problems using operator splitting solution strategies as are common with multi-physics problems. In FEAP the operator splitting is defined using partitions.

Plotting Results

FEAP has a time history output mechanism called tplot.

Parallel Runs

Collection files for paraview

When making parallel runs, it is desirable to merge the results into a single view for visualization. If one uses the PVIEw,time Marco command at the end of each time step, this will output paraview files per processor (with time stamps). These can then be viewed if one makes a paraview Collection File.

Paraview Files

Compressing VTU files

By default, the PVIEw command in FEAP creates non-compressed ASCII VTU files. For large models, this may lead to very large VTU files. In these cases, compressing the ASCII VTU files into Binary VTU files using a proper compressor, results in around 80-90% of reduction in the final size of the post-processing data. Here, a Python script is provided which helps the user with this task. PythonCompressVTUFiles
