The following tutorials are designed for new FEAP users to gain a deeper understanding of some important capabilities/features of FEAP.
Introduction
FEAP Basics
Batch commands needing user input
If you want to use a command in BATCh mode that requires user data, you need to place the data after the END.
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.
Time History Plots
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.
FE2 Computations
Isogeometric Computations
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
