fixed domain

For the "fixed domain" method, the motion of the nodes is governed by Equation 35–1. As a result, all of the nodes of the domain remain fixed at their original coordinates. This motion is applied on all topological entities included in the domain definition (that is, surfaces, lines, and points). Hence, it is not possible to apply another motion on these entities during the motion definition of an adjacent domain.

rigid translation

For the "rigid translation" method, the motion of the nodes is governed by Equation 35–2. This motion is applied on all topological entities included in the domain definition (that is, surfaces, lines, and points). Hence, it is not possible to apply another motion on these entities during the motion definition of an adjacent domain.

elastic remeshing

For the "elastic remeshing" method, the motion of the nodes is governed by Equation 35–3. This equation requires boundary conditions, which for 3D domains can be selected from the surface transformations described in Surface Transformations, and for 2D domains can be selected from the line transformations described in Line Transformations.
