Solution files

FELiCS exports computed mode shapes and harmonic responses in individual .h5 files.

These files are produced by:

• "Modal" analyses,

• "Resolvent" analyses,

• "InputOutput" analyses.

chosen with Case.AnalysisMode.

Contents

Solution files contain complex fields associated with the computed solution:

Analysis type	File contents
"Modal"	Eigenmodes associated with the computed eigenvalues
"Resolvent"	Forcing and response singular vectors associated with the computed gains
"InputOutput"	Complex harmonic response fields

The exported fields correspond to the fluctuating variables of the FELiCS state vector, as defined by SetOfEquations.

The fields are exported on the FELiCS output mesh.

Complex fields are stored by separating their real (variable_real) and imaginary (variable_imag) parts.

File naming

FELiCS generates solution file names from:

• the analysis type,

• the mode type,

• the angular frequency or eigenvalue,

• and, for resolvent analyses, the gain number.

Typical examples are:

Analysis type	Example file name
"Modal"	Mode_Modal_Adjoint_Omega_0.727-0.001j.h5
"Resolvent"	Mode_Resolvent_Forcing_Omega_0.700_GainNb_0.h5
"InputOutput"	Mode_Input_output_Response_Omega_628.319.h5

Attributes

Solution files include metadata attributes describing the exported mode.

Typical attributes include:

Attribute	Description
omega	Angular frequency or eigenvalue associated with the mode
m	Wavenumber associated with the spectral direction
gain	Gain associated with the mode, for resolvent and input/output analyses
number	Gain number, for resolvent analyses
