      Hello,

      I am trying to model the interaction between a numerical wave tank and the soil bed to examine the changes in pore pressure. The soil mesh is coarse compared to the ICFD mesh and both sit at the coordinate Z=0. Since the nodes do not align perfectly with one another, will they interact with one another correctly?

      Thank you.

      In my experience the nodes do not need to match, however the solver does require the distance between the fluid and solid mesh nodes to be < 0.25*(min element size of entire model). More details for this can be found in the LSTC ICFD theory manual you can easily find online.
