Introduction of background knowledge regarding flow physics and CFD as well as detailed information about the use of AcuSolve and what specific options do.
Collection of AcuSolve simulation cases for which results are compared against analytical or experimental results to demonstrate the accuracy
of AcuSolve results.
Mesh attributes control various aspects of the mesh generation process, including mesh size. Mesh attributes can be
set on a global (whole model) and/or local (model entity) basis.
Mesh size can also be specified as a function of location. Geometric shapes such as spheres,
boxes and cylinders can be drawn and mesh sizes are specified for the volume enclosing these
Zone Mesh Attributes.
The Global Mesh Attributes represent mesh settings that are applied to the entire model. Additionally, the
size specified in this panel is used as the global mesh length scale that is used in the octree method when
evaluating all subsequent mesh sizes.
Every geometric model in AcuConsole contains one or more volume groups. The pipe example model has one volume group called fluid with one geometric
region.
Once the geometry is imported into AcuConsole, it will have one or more surface groups. Each of the surface groups could have one or more geometric faces
associated with it.
The pipe example will again be used to demonstrate the usage of a spherical zone mesh
refinement.
To create a new zone mesh attribute, right-click on Zone Mesh
Attributes under Global and select
New.
Once a new zone mesh attribute is created, zone mesh types appear. Different
inputs are required to construct the primitive shape of the various refinement
region types. For a spherical zone, the center of the sphere and its radius are
required.
Click Open Array.
For the case of a sphere, this array defines the center of the sphere (Center
array).
In the Spherical Zone panel, the Radius is set to 0.01m and the Mesh size is set to
0.0015m. The center of the sphere is kept at (0,0,0) which corresponds to the center
of the inflow surface, as shown below.
Once the mesh is loaded into AcuConsole, the finer mesh
on the inflow surface in the spherical zone can be seen, as shown below.
