 The flow (water, air, temperature) description can be different from the mechanical description:​ the pressure/​temperature can be linearly interpolated in a 4-nodes configuration,​ while the mechanical DoFs are parabolically interpolated in an 8-nodes configuration. In that case, the flow DoF must be fixed for the nodes that are not used (2, 4, 6, and 8). \\ \\  The flow (water, air, temperature) description can be different from the mechanical description:​ the pressure/​temperature can be linearly interpolated in a 4-nodes configuration,​ while the mechanical DoFs are parabolically interpolated in an 8-nodes configuration.
