Configuring the modeling chain with param.ini file
Tip
The different parameters used by the modeling chains all have default values, so that none of the possible entries is required.
Info
All set of parameters used in ZephyFarm sub-applications may contain some comment entries. These entries are only used by the web-client and are not processed by the modelling chain.
Danger
The default sets of parameters proposed in ZephyFarm sub-applications may contain entries set between % characters (ie. wrg_heights=%heights%).
These entries are to be modified by the web-client on a latter stage.
If the entry set with a value, the value will be applied and the project will differ from how it was defined in the app.
The parameters are gathered in various subgroups:
-
Configure: parameters used during the configuration step.
-
Mesh-M1-*: parameters used by during the mesh generation step.
-
Calc-C1-*: parameters used by the "calc_C1" step
-
[Extern]: parameters defining the configuration of the extern programs (as OpenFoam)
-
[Client]: defines the execution client used to run the modeling chain
-
[Pictures]: parameters defining the visualizations
-
[Company]: information related to the company
-
[Project]: information related to the project
-
[Zephy*]: chain related parameters
-
[AutoConf]: parameters defining how the mesh and the calculation parameters will be automatically chosen in the case they are not provided as arguments to the program
