An ex vivo sheep model was established to compare the tissue penetration depth of the 6 prototype and the final design incorporated into a sheep harness. Numerical computation is performed in a static way, meaning that the kicking system evolution can be considered as a succession of short time independent magneto-static problems. this example, we will consider the case in which a steady current of 1 Amp is flowing through the wire. In 3d simulation I get maximum velocity 0. Lyon, Paul E. In this paper, the stability of the plane free surface is investigated theoretically when. The accuracy of the formulation is demonstrated by solving several practical engineering problems and comparing the BIE solution to analytical or other numerical methods such as the FEM. A typical example problem is used to compare results from the axisymmetric analytical equations that are derived with those from axisymmetric finite-element analyses.
