Descriere
Aplică o constrângere de presiune pe o fațetă.
Cum se folosește
- Click pe
sau alegeți Model → Mechanical Constraints → Constraint pressure din mediul de sus. - Click on Add reference și selectați fațeta în vedere 3D
- Editați fereastra corespunzătoare pentru a specifica presiunea în MPa
- Bifați caseta pentru a inversa direcția, dacă este necesar.
Pressure load applied to a cylinder
Properties
- DateEnable Amplitude - introduced in 1.1: Enables the use of CalculiX's amplitude for the time variation of the pressure load. At a given time, magnitude of the load is multiplied by the amplitude value corresponding to that time. Linear interpolation is used between the specified values. Constant values are used outside of the specified range.
- DateAmplitude Values - introduced in 1.1: Amplitude table in the following format:
time_1, amplitude_value_1 …
- Default is linear increase from 0% at t=0 to 100% at t=1:
0, 0 1, 1
Note
Distribuția presiunii este întotdeauna uniformă și întotdeauna perpendiculară pe față.
- 0.21 and below: Pressure load can be applied to shells but only when Gmsh is used for meshing and group meshing is set to true. It is hardcoded as true so the user doesn't have to worry about that. However, due to a bug, pressure load may require remeshing to work on shells.
- This feature uses the *DLOAD card in CalculiX.
