8.1. Tested values of C, E modeling#

The calculation is non-linear because of the shock and no analytical solution is available. We therefore test the calculation on non-regression values on the displacement along \(x\) of the node \(\mathrm{NO2}\).

We compare the absolute movements from DYNA_NON_LINE with keyword SCHEMA_TEMPS (FORMULATION =” ACCELERATION “) with those given by DYNA_NON_LINE with keyword SCHEMA_TEMPS (FORMULATION =” DEPLACEMENT”).
