+====== Quasi-static integration schemes ======
+===== Description =====
+In this case, inertial forces $F^{inert}$ are neglected. The equation $F^{int}=F^{ext}$ is then solved iteratively for each time test required.
+===== Data set =====
+=== Old Metafor Version <= 2422 ===
+No commands are required, quasi-static integration is the default one. If the parameter ''MDE_NDYN'' is defined in the test case, its value must be 0.
+=== New Metafor Version > 2422 ===
+The quasi-static time integration procedure is the default one in Metafor. Even so, you can specify it in the dataset, as follows :
+<code>
+ti = QuasiStaticTimeIntegration(metafor)
+metafor.setTimeIntegration(ti)
+</code>
+===== Useful parameters =====
