Subject: Pressure mapping using *Moper for rectangular pontoon hull Author: Xiaoping Yang Date: 2002-11-12 17:03:00Hi, I read some articles regarding *MOPER command used in surface pressure mapping. It seems that it only works for one surface each time. For example, in case of pressure over two perpendicular crossed planes, it might be necessary to map two planes one by one. If my understanding is correct, it might be troublesome to deal with a big model like a rectangular pontoon hull. In that case each plate needs to be isolated from other parts of the model during pressure mapping. Although I can write a macro tailored to the needs of pontoon case, I hope I can do a global mapping for all the surfaces in the model one time. And I don't know if that function is available in ANSYS 6.1.
Also I wonder if anyone here can tell me about the triangular interpolation method applied in *MOPER command. Quite interesting in that subject.
In addition, I would have seen a message that read "Output point # is not inside region. Values at nearest input point # is used" when I did some playing with my pontoon mesh. I understand when I tried to map the pressure from a coarse mesh to a finer mesh, I would always get that kind of warning message as I use pressure results at centroids of shell elements as mapping inputs. So, Can I just simply disregard that warning message? I feel a little insecure to use that result.
