KTex Pattern is part of the KTex Family. It is launched from HyperMesh as a TCL script. It aims at building finite element (FE) models of any kind of weave (1D, 2D and 3D). To do so, some inputs are required, such as dimensions of the fibers, the desired weaving pattern, the material of the fibers, the type of elements to mesh the fibers and the desired size of weave. With all these parameters, a FE model of the weave is automatically generated and meshed. A database of many fiber cross sections is available, but bespoke cross sections can be generated. Fibers can be meshed with shell or solid elements. The user has the choice to generate only the Representative Elementary Volume of the weave, or to specify rectangular dimensions, or even to use a line created in HyperMesh in order to fill it with the described weave. A database of commercial weaves is available in the software but bespoke patterns can be generated. Several plies can be stacked on top of each other, mixing all the different possibilities of the software. An angle can be defined from one ply to the other. This gives the possibilityy to generate many kinds of stacks, potentially including patches. Attached is an overview video of the software capabilities.

KTex LayUp is dedicated to representing one of the composite materials manufacturing processes: the moulding or RTM process. To do so, the fabric has to be compressed between a cast and a die. Usually, to simplify the numerical simulation, the cast and the die present very close geometries. KTex LayUp automatically creates one from the other. The user has the possibility to use any existing model of one of the two in KTex LayUp. The tool will automatically create the complementary shape and translate it before launching the simulation. The attached video is a tutorial to create a bespoke mould geometry to be sure it will be usable in KTex LayUp. KTexLayUp_Mold_creation_v2.mp4
KTex LayUp is dedicated to representing one of the composite materials manufacturing processes: the molding or RTM process. Its main objective is to automatically set-up a ready-to-run finite element model simulating this process. To do so, two input parameters are needed: the fabric and the mold. Some molds and fabrics are included in the tool database, but bespoke ones can also be created. A video regarding mold creation will come later. When selecting a fabric, two options are available: REV or Size/Shape. The REV option only needs the Representative Elementary Volume of the fabric. This REV is then duplicated and translated as many times as needed to be bigger than the mold. But the final geometry of the fabric to be molded will always be a square. The Size/Shape option needs the geometry of the fabric to be molded. This fabric can be a stack of several plies. It can feature several plies of different geometries, thicknesses or patterns... Anything is possible in order to represent the real plies that are to be molded. The user is free to define the fabric, but the user has to be careful as mistakes will not be detected. The attached video gives an example of the difference between the two options. KTexLayUp_REVvsSHAPE.mp4
