This article explains how to compile a user-creep subroutine and create a .dll file that can be used to run a creep analysis in SOL401.
This option is required only if the user-creep subroutine has the creep law defined but not the creep coefficients
This option sets all data (nodal coordinates, material data, magnitude of loads and BCs) that are below ‘Real Data Filter Value’ to 0. Sometimes, the material properties like creep can be in the order of 1e-50 or lower, and this can make the results inaccurate.
Note: If you are solving using a different method (command line, Remote Solve or Nastran.exe window), make sure to specify the location of DLL file using keyword ‘ucrplib’
ucrplib=*location of .dll file*
