【正文】 e of the singlestrandedmelts evolved along the upper and lower surface of the coordination of the flow flow of technologys biggest advantage is that the model greatly shortenthe preparation time thus greatly reducing the burden on the user modeling will takeseveral hours or even days of the original modeling work reduced to a few based on doublesided flow simulation software technology although theadvent of time only a few years but in the world but has a huge user base get themajority of customers for their support and the doublesided flow of technology has the following deficiencies:1 The twosided flow of technology does not fundamentally resolve the issue of aneutral face they still can not describe some threedimensional features such as theinertial effect can not describe gravity effect on the melt flow which fail to predict jetphenomenon melt cuttingedge Quanyong the upper and lower surfaces corresponding to the melt flow front there aredifferences. As the upper and lower surface of the grid can not be one correspondencebut the grid shape orientation and size can not be pletely symmetrical so how theupper and lower surfaces corresponding to the difference between the melt flow frontcontrol is within the scope permitted by Difficulties in the implementation ofdoublesided streaming melt is only along the upper and lower surface flows in the thickness direction isnot to make any treatment lack of Moldflows 3D analysis techniquesThese two techniques have overlooked the thickness direction of the physical quantityonly twodimensional simulation and therefore results are not very precise. MoldflowCorporations 3D 3D analysis technology uses a true threedimensional solid modelflow analysis techniques through rigorous theoretical derivation and repeatedverification the inertial effect nonisothermal flow taking into account factors suchas finite element analysis the melt thickness direction of the physical quantitychanges will no longer be ignored can be a more prehensive description of theprocess of filling flow phenomena so that results of the analysis more realisticconditions applicable to all plastic products. Its threedimensional grid is from thefournode tetrahedron unit. And using the new 3D stereoscopic display technologycan quickly model clearly shows that internal and external flow field temperaturefield stress field and velocity field such as analysis results. For the abovementionedresults of the analysis can also be used such as bit lines or equipotential surfacedisplay so that physical models and external changes in the variables show moreclearly the case Moldfiow also offers animation capabilities through 3D animationdisplay plastic melt in the changes in the flow cavity allowing users to moreintuitively see the design and manufacturing process may encounter the 3D technology meshing demanding more plex equations to calculate theamount of large long duration and the putational efficiency is low not suitablefor short development cycle and need to be repeatedly revised by CAE verificationinjection mold
