Analysis

General

• Error during modal analysis

• Warning: stiffness matrix is singular, structure is unstable

• Warnings 'No nodes found in project data' and 'Mesh generation: not ok'

• Obtain the response of a structure as a function of the applied frequency

• Incorrect 2D slab topology

• Message: there are elements having an angle smaller than 5 degrees

• Limitations of nonlinear calculations

• Frequent sources of instabilities

• Automatic calculation of effective width

• Exceptions for antivirus

• Batch analysis via ESA_XML

• Error: unsupported waveform of a nonlinear function

• Use model modifiers to create a staged project

• Warning about imperfections and free loads (Incompatibility in input data)

• Global imperfection for a scaffold structure

• Check (convergence of) nonlinear analysis

• Combine nonlinear combinations with seismicity

• Improved Reduced System (IRS)

• Solver precision ratio

• Determination critical load coefficient

• Second order analysis

• Instability when having axial force only members
