FEM SolverCalculixCxxtools/it

Descrizione
CalculiXccxTools abilita l'uso del solutore CalculiX. Può essere usato per
 * 1) impostare i parametri dell'analisi
 * 2) selezionare la directory di lavoro
 * 3) eseguire il risolutore CalculiX.

Utilizzo

 * 1) L'oggetto  viene creato automaticamente con la creazione di un . Altrimenti usare  → , o premere i tasti  e poi
 * 2) Facoltativamente, impostare le proprietà dati degli oggetti
 * 3) Fare doppio clic sull'oggetto
 * 4) Selezionare il tipo di analisi
 * 5) Cliccare
 * 6) Cliccare

Opzioni
Usando è possibile visualizzare e modificare manualmente il file di input CalculiX prima di eseguire l'analisi. In questo caso può essere utile usare il parametro "Split Input Writer = true".

Proprietà
I valori predefiniti possono essere impostati nel menu →  →  →


 * statico
 * frequenza
 * thermomech - per carichi meccanici e termici
 * thermomech - per carichi meccanici e termici


 * : note that CalculiX internally expands 1D and 2D elements into 3D elements to accomplish FE analysis
 * false - results of 1D and 2D elements will be averaged to the nodes of original 1D or 2D mesh (i.e. purely bended beam will show 0 nodal stresses due to averaging)
 * true - resulting mesh will contain 1D and 2D elements expanded to 3D elements


 * : Eigenvalues above this limit will not be calculated


 * : Eigenvalues below this limit will not be calculated


 * : number of lowest eigenmodes to be calculated


 * linear - linear analysis will be performed if model does not contain nonlinear material
 * nonlinear - nonlinear analysis will be performed
 * nonlinear - nonlinear analysis will be performed


 * : defines second line of advanced iteration parameters under *CONTROLS card, used when "Iterations Control Parameter Time Use" is true


 * : defines first line of advanced iteration parameters under *CONTROLS card, used when "Iterations Control Parameter Time Use" is true


 * true - activates "Iterations Control Parameter Cutb" and "Iterations Control Parameter Iter"
 * true - activates "Iterations Control Parameter Cutb" and "Iterations Control Parameter Iter"


 * : maximum number of increments in thermomechanical analysis after which the job will be stopped.


 * true - automatic incrementation control will be switched off by DIRECT parameter
 * false - incrementation control will be automatic
 * false - incrementation control will be automatic


 * true - activates "Time End" and "Time Initial Step" parameters
 * true - activates "Time End" and "Time Initial Step" parameters


 * linear - only linear material properties will be included in the analysis
 * nonlinear - nonlinear material properties will be used from object
 * nonlinear - nonlinear material properties will be used from object


 * : type of the solver to solve equation system inside FE analysis. It may significantly affect calculation speed and memory demands. Suitability depends on your FE model and available hardware
 * default - automatically selects matrix solver depending on available solvers (probably it will be Spooles)
 * spooles - direct solver with support of multiple CPUs. Number of CPUs need to be set in →  →  →  → Solver defaults → Number of CPU's to use)
 * iterativescaling - iterative solver with least memory demands, suitable if model contains mostly 3D elements
 * iterativecholesky - iterative solver with preconditioning with and with low memory demands, suitable if model contains mostly 3D elements


 * false - write whole input into one *.inp file to be used by CalculiX solver
 * true - split solver inputs into more *.inp files, that can clarify hand editing
 * true - split solver inputs into more *.inp files, that can clarify hand editing


 * true - steady state thermo mechanical analysis
 * false - transient thermo mechanical analysis
 * false - transient thermo mechanical analysis


 * : time period of the step, used when parameter "Iterations User Defined Incrementations" or "Iterations User Defined Time Step Length" is true


 * : initial time increment of the step, used when parameter "Iterations User Defined Incrementations" or "Iterations User Defined Time Step Length" is true


 * : path to the working directory which will be used for CalculiX analysis files.
