Hi,
I am trying to convert an AQWA mesh to MOSES. Appreciate if you can advise why the result for buoyancy seem to be negative? and what need to be corrected? Thanks
Hi Naim,
This is probably due to the incorrect panel orientation. The MOSES convention states that when defining a panel, the order of vertices should be clockwise when the panel is viewed from the outside of the body. I believe that when you converted from AQWA mesh to MOSES, it was in the opposite direction to the MOSES convention.
You can simply change the direction by using the "REVERSE -yes" command just before the panel definition, as shown in the code below. I hope this helps.
