Airfoil (Recover)

Dehomogenization workflow built on top of the MH-104 example.

Overview

This example continues from the previous one to demonstrate the dehomogenization analysis. It is assumed that a 1D beam analysis has been finished, and data of global deformations and loads have been added to the main input file correctly (See the recover section). Suppose that the results in Sectional forces and moments are used and default values are kept for others. All files generated from the VABS homogenization analysis are kept in the same place as input files.

Table 27 Sectional forces and moments

Quantity	Value
\(F_1\), N	1
\(F_2\), N	2
\(F_3\), N	3
\(M_1\), Nm	4
\(M_2\), Nm	5
\(M_3\), Nm	6

Output note

--dh writes the global-load auxiliary file used by VABS for recovery, -e executes the recovery analysis, and -v opens Gmsh to display the recovered fields. To only generate the auxiliary file without executing or plotting, drop the -e -v flags.

The key additional output is mh104.sg.glb.
