Cross-Section Elastic Buckling Analysis

Calculate cross-section elastic buckling modes with the finite strip method. This is a direct translation of CUFSM v5.04, without constrained finite strip (cFSM) functionality.

Example Usage

using CUFSM

Run the CUFSM default buckling analysis that comes up when you open the program.
