    Currently trying to evaluate the resistence and power prediction of a multihull using Maxsurf Resistance. Since the length to beam ratio is more than the usual 6-7, I thought of using the slender body method. When I display the default mesh (which usually is more than enough) it doesn't look like anything I would expect. Any tips on the reason to this disaster?

    Managed to partially solve the problem. Now, the thing is that the slender body mesh doesn't mirror on the second demihull. Any way to solve this?

    This is the SB Mesh I get after deleting symmetrical surfaces. The mesh looks correct.

    Wow, much appreciated. Thank you very much.

    Sorry but I'm a beginner. What do you mean by deleting symmetrical surfaces? What should I do to avoid this? It's so that I don't get the same problem in the future.
