2016年2月8日 · Just for clarification, ANSYS CFX never converts the original mesh into a polyhedral mesh explicitly, i.e. it discretizes the equation on each element sector around a node, and creates discrete equations around a node of the original mesh.

2006年3月25日 · To discretize momentum equation, one needs pressure values on the control volume faces. Standard pressure discretization interpolates the pressure on the faces using the cell center values. On the oth

ANSYS Meshing & Geometry Discussions about ANSYS Meshing, DesignModeler, ICEM CFD, TGrid, GAMBIT and other meshing and geometry tools from ANSYS. [ICEM] smooth the mesh

2016年11月10日 · Hi, Double precision will be significant if tiny relative differences are significant. Examples where you would expect double precision to make a difference are natural convection (especially if modelled with the fully compressible option); meshes with a large difference between the largest and smallest element sizes; large geometries with small but significant features; …

2014年5月20日 · Hey guys, i have a question according Fluent. I already finished some transient simulations with 5000 time-steps.

2004年6月29日 · I have developed a FORTRAN subroutine to use as a junction box in ANSYS-CFX, I compiled the code, but once I tried to run the simulation I get following errors: +-----+ | ERROR #001100279 has occurred in subroutine ErrAction.

2018年10月7日 · Hey, welcome to the world of CFD. Short answer, yes, mesh size is really important and there are a few equations (like in turublence, the calculation of the y+ value, and the Flow Courant Number) that you can use depending on your flow conditions to maintain a …

2008年2月7日 · I am struggling with same problem. If you find the answer please let me know how you resolved the issue. By the i am using upwind scheme and small physical time step (for steady state) to run the case and it seems to be working for now.

2020年7月21日 · Hello Ryan, That difference usually show up when you make polyhedra mesh in fluent (e.g you've created your mesh then opened Fluent, you can convert your mesh to polyhedra with a single button in Fluent and it can not be converted back).

2013年12月7日 · I want to simulate a turbulent flow in a rectangular channel, what is the difference between pressure outlet and outflow in bondary condition.
