  • Before we develop LVAFoam, a CFD software for launch vehicle analysis, we conducted a survey on other CFD softwares. We looked at in-house code and commercial CFD software of other countries that were used as a simulation of launch vehicle's combustor, turbopump and external flow. This research included in-house code solvers, developed by NASA, Mississippi State University, DLR, Bertin Technologies, CNES, CERFACS, and JAXA as well as commercial CFD software from FLUENT, CFX, Advance/FrontFlow/red, GASP, CRUNCH CFD, CFD-ACE+, FINETM/Turbo, STAR-CCM+. The simulation cases of launch vehicle analysis from each commercial softwares and introduction of the LVAFoam were presented.

  • With the increasingly diverse, sophisticated and complex character animations that can be represented in 3D animations, the importance of rigging, which can most directly affect animating quality, is becoming more and more important. In addition, rapidity is another crucial aspect of 3D animation production. So, the importance of technical director's role which is accurate and rapid handling of rigging pipeline building and immediate application and, corrections of errors during the longest and manpower consuming animation production is more becoming key. Baek Ji Won and Kim Jae-woong (2014) said, "The technical director is adding new importance to the new job, which is created by 3D animation, in conjunction with the limited production period, manpower, budget and production process." Most major overseas studios are developing in-house software to handle rigging and animation processes. Software development code is used to freely develop and modify production pipelines in accordance with the direction of the work. They are making efforts to build an optimal environment for animators. However, too many efforts and ineffective efforts have been made to develop, adapt, and stabilize the rigging process for small producers, creators, and students who do not have the capacity to develop their own in-house software or hire a technical director. This study suggests the most suitable auto-rigging tool among the many auto-rigging tools released in the market, and suggests the most accurate and quick auto-rigging process setting method for those who have insufficient knowledge about 3D character rigging. The efficiency of use of auto-rigging tool was examined.
