History:

  1. 1.0.0 - Initial Module Creation

Todo:

update_gauge.update_gauge(gauge, ms, beta, gauge_min, gauge_max, mstar)[source]

update gauge

\begin{gather} g^{k+1} = g^{k} \left(\frac{1.0 + \overline{MS}}{1.0+MS^{k}}\right) ^ \beta \end{gather}
Parameters

  • gauge (float) – structural gauge at current step

  • ms (float) – minimum margin of safety

  • beta (float) – overcorrection rate

  • gauge_min (float) – minimum value of structural gauge

  • gauge_max (float) – maximum value of structural gauge

  • mstar (float) – target value of margin of safety

Returns

structural gauge at next step

Return type

gauge_next (float)

update_gauge.main()[source]

main sequence

Procedure:

  1. read BDF, minimum MS, current gauge

  2. check convergence

  3. update gauge if convergence is not achieved

  4. export next gauge

Input files:

  • ‘mesh_property_load_gauge.bdf’ (ASCII): bulk data of structural mesh

  • ‘gauge_shell.csv’ (ASCII): thickness of each shell property

  • ‘gauge_rod.csv’ (ASCII): are of each rod property

  • ‘gauge_minmax.csv’ (ASCII): lower and upper limit of structural gauge

Output files:

  • ‘gauge_shell.csv’ (ASCII): thickness of each shell property

  • ‘gauge_rod.csv’ (ASCII): area of each rod property

  • ‘gauge_shell.hdf5’ (binary): history of shell thickness

  • ‘gauge_rod.hdf5’ (binary): history of rod area

  • ‘check.hdf5’ (binary): history of gauge, ms, bool

  • ‘sizing_bool.hdf5’ (binary): history of convergence
