- [ANSYS Meshing] Failed Mesh Poor Quality Mesh
So once I did face this problem in a large assembly with multiple parts in a wide range of sizes The mesher successively failed although repair geometry could help solve problem in the Space Claim Geometry interface in ANSYS 18 1 by creating solid bodies from surfaces
- ANSYS fluent and OpenFoAM comparison - CFD Online
Console output of ANSYS fluent: Ansys fluent console output png Console output of Openfoam: Openfoam console output png-----Do linear solvers affect the output of a cfd simulation? i e oscillation occurs for OF but not ANSYS in my simulation when I use a turbulence model with exactly the same input Setup for ANSYS fluent: Realizable K-e

- CFX vs. FLUENT -- CFD Online Discussion Forums
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
- standard Vs PRESTO! scheme -- CFD Online Discussion Forums
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
- Single v. s. double precision -- CFD Online Discussion Forums
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; flows with large
- [ANSYS Meshing] Mesh failed error:surface mesh is intersecting or close . . .
Ansys mesh the surface mesh is intersecting or close to intersecting making it difficult to create a volume mesh please adjust the mesh size or adjust the geometry to fix the problem message 2: A mesh could not be generated using the current meshing options and settings See screenshot attached
- Determining Ideal Mesh Size -- CFD Online Discussion Forums
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 good equation
