4、e,Produced by the ANSYS CFX-Solver and contains information about your simulation:,a)Model set-up,b)The state of the solution during the run,c)Job statistics for the particular run,Now lets take a detailed look at an out file,CFX-Solver,CFX-Pre,CFX-Post,.def,.res,.cfx,.cfx,.def,.res,.out,.gtm,.def,S
5、olver Information,a)Model Setup,The out file,Physics definitionCFX Command Language(CCL),a)Model Setup,If an Initial Values file is provided,the Interpolator will run to copy/interpolate variables,b)Interpolator,Memory requirements shown here are for the interpolator only,Details of the interpolatio

7、ection details are shown here,188 MB of RAM allocated,The start of the Solver process,Memory requirements shown here are for the Solver.If memory errors occur check if its the Interpolator,Partitioner or Solver process,Diagnostics shown as the solver iterates towards a solution,Upper case“OK is good
8、.Lower case“ok means youre on the limit.“F means failed to solve the equation.Reducing the timestep may help avoid“ok and“F.The first few iterations may show“ok and“F and can be ignored as long as they go away,e)The State of the Solution,When the solution finishes the Imbalances are shown,Equation I
9、mbalance in domain,f)Final Imbalances,Other data printed at the end of the out file include Viscous and Pressure forces and torques on walls,min/max variable values and detailed CPU requirements,g)Other Solution Data,Key Point,The.out file contains information on the physics,solution progress,and ex
10、ecution control.,CFX Command Language,object definition language which underlies all CFX products,Object parameters define the“state of an object,GUIs present object parameters in a contextual manner(parameters shown/hidden based on GUI selections),Allows for easy modifications,E.g.modifying an inle
11、t velocity at a boundary,Advanced functionality(without complexity),i.e.loops and logic,CCL Command Interpreter,User Input/Interface,Processing Engine,What is CCL?,CCL Statements can be classified into three categories:,Object and parameter definitions,Actions,Power Syntax,1.Example of Parameter Def

13、rameter Value,CCL follows a data hierarchy.In order to specify the Temperature,the associated parents(Boundary,Domain,Flow)must be included,As long as the parameters are of the same object,order is unimportant,An object started must be ended,If data is set in one place and modified in another,the la

16、space.,CCL names definition,In simple syntax,a CCL name must be at least one character.,This first character must be alphabetic;there may be any number of subsequent characters and these can be alphabetic,numeric,space or tab.,Continued on next slide,Syntax,Parameter Values,STRING,The characters$and#have a special meaning.A string beginning with$is evaluated as a Power Syntax variable,even if it occurs within a simple syntax statement.,The characters such as,and are special only if used in conju
