Computer Aided Structural Analysis

CASA Intuition CASA-M logo

The features are a subset of those of CASA-M. It carries the following restrictions relative to CASA-M:

  • Numerical output does not reflect actual analysis results; the numbers are normalised for the purposes of comparative study of the behaviour and force distribution of the structure under load, and cannot be used for subsequent calculations, checking, or design.
  • Saved files are only compatible with CASA Intuition and there is no file transfer with the mobile CASA Apps.
