摘要
It is the main object of the instant invention to describe a new method to use surface models for simulation of fluid within thin-walled three-dimensional geometries avoiding the generation of a midplane or using a standard volumetric mesh. According to the invention, this main object is reached in that for getting a numerical information of the local part thickness a first defined thickness is achieved by measuring the length of a vector starting from the centre of gravity of each polygon normal to the element plane in the direction to the inside of the part until the vector leaves this part, that the surface mesh is filled with a framework of rod elements extending from node to node of the polygons through the part's inside within reasonable low distance from the normal direction and that the injection point(s) is/are integrated into the mesh at any place on the polygons or the nodes of the Finite Elements mesh.
