4. B modeling#

4.1. Characteristics of modeling#

The calculation is done in non-linear heat, with \(\theta =0.57\).

We do 1 time step from \(0\) to \({10}^{–9}s\) and \(300\) time step from \({10}^{–9}s\) to \(1.5{10}^{–5}s\)

The results are reviewed in \(t\mathrm{=}1.5{10}^{–5}s\).

4.2. Characteristics of the mesh#

4 QUAD8, 4 SEG3, 26 knots

4.3. Tested values#

4.4. notes#

The precision required on the results is only \({10}^{–3}\) (instead of \({10}^{–6}\) in linear) because we have not yet, at \(t=1.5{10}^{–5}s\), rigorously reached the steady state.
