Descripción
CalculiXccxTools permite usar el solucionador CalculiX. Puedes usarlo para
- configurar los parámetros de análisis
- seleccionar directorio de trabajo
- Ejecutar el solucionador de CalculiX.
Utilización
- CalculiXccxToolsobjeto se crea automáticamente con la creación de Analysis container. De lo contrario utilizar Solve → Solver CalculiX Standard , X keyso presione S luego las teclas X
- Opcionalmente, configure las propiedades de datos del objeto CalculiXccxTools
- Haga doble clic en el objeto CalculiXccxTools
- Seleccione el tipo de análisis
- Haga clic en Write .inp file
- Haga clic en Run CalculiX
Opciones
Al usar Edit.inp file puede mostrar y editar el archivo de entrada de CalculiX manualmente antes de ejecutar el análisis. En este caso, puede ser útil usar el parámetro "Split Input Writer = true".
Propiedades
Los valores por defecto se pueden configurar en el menú. Edit → Preferences → FEM → CalculiX
- DatosAnalysis Type:
- estática
- frecuencia
- Thermomech - para cargas mecánicas y térmicas.
- DatosBeam Shell Result Output 3D:
tenga en cuenta que CalculiX expande internamente los elementos 1D y 2D en elementos 3D para realizar el análisis FE
- falso: los resultados de los elementos 1D y 2D se promediarán a los nodos de la malla 1D o 2D original (es decir, el haz puramente curvado mostrará 0 esfuerzos nodales debido al promediado)
- verdadero - la malla resultante contendrá elementos 1D y 2D expandidos a elementos 3D
- DatosEigenmode High Limit: Los valores propios por encima de este límite no serán calculados
- DatosEigenmode Low Limit: Eigenvalues below this limit will not be calculated
- DatosEigenmodes Count: number of lowest eigenmodes to be calculated
- DatosGeometric Nonlinearity:
- linear - linear analysis will be performed if model does not contain nonlinear material
- nonlinear - nonlinear analysis will be performed
- DatosIterations Control parameter Cutb: defines second line of advanced iteration parameters under *CONTROLS card, used when "Iterations Control Parameter Time Use" is true
- DatosIterations Control Parameter Iter: defines first line of advanced iteration parameters under *CONTROLS card, used when "Iterations Control Parameter Time Use" is true
- DatosIterations Control Parameter Time Use
- true - activates "Iterations Control Parameter Cutb" and "Iterations Control Parameter Iter"
- DatosIterations Thermo Mech Maximum: maximum number of increments in thermomechanical analysis after which the job will be stopped.
- DatosIterations User Defined Incrementations:
- true - automatic incrementation control will be switched off by DIRECT parameter
- false - incrementation control will be automatic
- DatosIterations User Defined Time Step Length:
- true - activates "Time End" and "Time Initial Step" parameters
- DatosMaterial Nonlinearity:
- linear - only linear material properties will be included in the analysis
- nonlinear - nonlinear material properties will be used from Nonlinear mechanical material object
- DatosMatrix Solver Type: 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 Edit → Preferences → FEM → CalculiX → 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
- DatosSplit Input Writer:
- 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
- DatosThermo Mechanical Steady State:
- true - steady state thermo mechanical analysis
- false - transient thermo mechanical analysis
- DatosTime End: time period of the step, used when parameter "Iterations User Defined Incrementations" or "Iterations User Defined Time Step Length" is true
- DatosTime Initial Step: initial time increment of the step, used when parameter "Iterations User Defined Incrementations" or "Iterations User Defined Time Step Length" is true
- DatosWorking Dir: path to the working directory which will be used for CalculiX analysis files.
