Read Local States

After dehomogenization and/or failure analysis, local state fields (strain/stress/displacement/failure index/strength ratio) of the SG can be read using the sgio.readOutputState() function.

Read VABS Element Local Strain and Stress Fields and Visualize in Gmsh

Consider the following VABS output file (sgio/examples/files/cs_box_t_vabs41.sg.ELE) after dehomogenization. This file contains the local strains and stresses of each element of the cross-section, in both the global and material coordinate systems.

To read the data, we need to first read the cross-sectional data using sgio.read(). Then read the local state fields using sgio.readOutputState(). The returned object is a list of N sgio.model.StateCase objects corresponding to N load cases.

Then, we need to add the local state fields to the cross-sectional data.

Finally, we need to write the cross-sectional data to a Gmsh file.

The following figure shows the visualization of the local stress field of the cross-section in the material coordinate system.
