The assumption of axisymmetry implies that there are no circumferential gradients in the flow, but that there may be non-zero circumferential velocities. Now, what is very important is that while we have elements only in 2D, we have nodes in 3D (see general axisymmetric elements and nodal planes). READ ANSYS Help: Mechanical APDL > Structural Analysis Guide > Modal Analysis, 3. A spherical pressure vessel with a cylindrical nozzle is analysed using the finite element method. I plan to give some background information on why 2D ANSYS may be thought as sufficient enough to represent the geometric of the blood vessel, rather than 3D.

If you can draw a line (axis) and the image is mirrored across that line, it is said to be axisymmetric. Convert 2D geometry to 3D general axisymmetric elements (geometric axisymmetry with non-axisymmetric loading). Planar indicates that the problem is two-dimensional. There are assumptions made in the math regarding the third direction. 2D-axisymmetric modeling in StarCCM+ Hey, it's me again from the aerospike project. Also, real life fillet welds are never a perfect triangle, so your results are not worth much unless you know what the stress intensification factor is. Since the cross-section of the solenoid is constant, it can be modeled as an axisymmetric model in Maxwell SV.

It is a way of modeling complex fluid flow by breaking down geometry into cells that comprise a mesh. Я тоже получил результат Г=0,17, П=0,34. As the object deforms radially, the math knows that there is a tangential resistance that creates stress in an object. On the other hand, Ansys provides some commands to expand the solution results of your cyclic symmetry analysis to the full 360º model (or to a certain integer number of basic sectors). 2D Model Overview • General model of a simple turbine Flowpath CDT/CDP Cold Bearing Buffer oil • Axisymmetric or Plane w/ thickness - SURF151 • To model convection/advection on • Coded in ANSYS Parametric Design Language (APDL).
