Save the case data
n Before mesh generation it is advised to save the data into .ecf file.
n The ecf file holds all the information for the ennovaCFD.
Volume mesher in ennovaCFD
n The Topology Based Mesh, which is based on the Delaunay method, is available in ennovaCFD for the volume mesh.
n Topology Based Mesh could be used to create models with multiple area, such as the fluid-solid heat transfer model.
n 
Creating the polyhedral mesh is also possible.
Button of Topology Based Mesh
Check it if polyhedral mesh is to be created （In the current case it should
Mesh generation of domain with multiple areas
Check the mesh numbers
n 
Here introduces the methods to check the mesh numbers
①：the total number of cells
②：triangular mesh（surface mesh）
③：square mesh（surface mesh）
④：tetrahedral mesh（volume mesh）
⑤：pyramid mesh（volume mesh）
⑥：pentahedron mesh（volume mesh）
⑦：hexahedral mesh（volume mesh）
Display a cut plane
n Here we introduce how to display a cut plane

Settings for the solver
n Once the volume mesh has been generated with ennovaCFD, we can start the settings of the solver, which will be done by Setup with Ennova Mesh.
Setting of the Physics n
n 
Property settings (1/3)
n FLUID (outer domain) will be set to be air.
Initial values (Use the default values)
Property settings(2/3)
n 
SOLID (heat sink) will be set to be Aluminum.
Property settings (3/3)
n HEAT (heat source) will be set to be Cell Zone. It will have the same properties with the SOLID
③：Select ”SOLID”
（HEAT belongs SOLID, i.e., they have the same physical properties.）
Setting the Boundary Conditions (1/3)
n 
Set the boundaries starting with Share~ to be Interface.
Setting the Boundary Conditions (2/3)
n OUTLET will be set to Total Pressure
Setting the Boundary Conditions (3/3)
n WALL will be set to No-slip Wall with Constant Temperature.

F) Convergence
n The criteria for convergence (When set to 0, the simulation will end until the specified iterations are practiced).
In this manual，except for ②～④
, default values will be used.
Setting the relaxation parameter
n In this manual, we use the default values.
A) Pressure
B) Flow
C) Turbulence
D) Energy (Fluid)
E) Energy (Solid)
F) Density
A B C D E F
Setting the Tolerance/Relative Tolerance Tolerance/Relative Tolerance of Pressure is set as follows.
Setting the algebraic solvers
