8. F modeling

This modeling is the same as the D modeling but in selective modeling. The integration is therefore different: the integration of the unsteady terms takes place at the nodes and that of the other terms at the Gauss points.

The results on one element therefore differ logically.

Table of results at different times:

\(N°\) KNOT	Order Number	\(\mathrm{PRE1}(\mathrm{Pa})\)	Tolerance \((\text{\%})\)
\(\mathrm{N20},A\)	1	\(8.79\times {10}^{-6}\)	\(5\)
	2	\(1.84\times {10}^{-4}\)	\(5\)
	3	\(6.24\times {10}^{-4}\)	\(5\)
	4	\(0.018\)	\(5\)
	7	\(6.20\)	\(5\)
\(\mathrm{N1},C\)	1	\(6.63\times {10}^{3}\)	\(5\)
	2	\(3.31\times {10}^{4}\)	\(5\)
	3	\(6.63\times {10}^{4}\)	\(5\)
	4	\(3.31\times {10}^{5}\)	\(5\)
	7	\(6.68\times {10}^{6}\)	\(5\)
