Re: How to get the surface normal vector
Thanks Alex. I want to set the BC in Pre using the surface normal vector. I read some old posts in this forum, one mentioned that the "Normal X" variable e.g., is only valid in Post. I tried to obtain the surface normal vector with User Fortran subroutine USER_GET_MESHDATA, but I failed with setting a correct LOCALE. The comment on this subroutine is not sufficient. I tried to read the LOCALE with the subroutine USER_CALC_INFO. However, the returned LOCALE by this routine can't satisfy the argument of USER_GET_MESHDATA with I try to use it on a wall boundary. Do you have any idea on that?
