Descriere
Constrângerea greutății proprii este definită de către accelerația gravitațională de 9,81 m / s ^ 2 care acționează asupra întregului model în direcția prescrisă.
version 0.21 and below: The acceleration has a fixed value of 9.81 m/s^2.
Cum se folosește
Script
- obiect nou
import ObjectsFem
ObjectsFem.makeConstraintSelfWeight(name)
- adăugați obiectul la analiza numită Analysis
App.ActiveDocument.Analysis.Member = App.ActiveDocument.Analysis.Member + [(object)]
- examplu:
import ObjectsFem
selfweight_obj = ObjectsFem.makeConstraintSelfWeight("MySelfWeightObject")
App.ActiveDocument.Analysis.Member = App.ActiveDocument.Analysis.Member + [selfweight_obj]
Solver CalculiX
Limitations
Solver CalculiX
Limite
- Trebuie să modificați fișierul .inp pentru a edita accelerația gravitațională.
- Gerutatea proprie este aplicată elemetului set Eall înseamnă întreg modelul .
Editing CalculiX input file
Editing CalculiX input file
Accelerarea constantă poate fi modificată prin modificarea manuală după generarea fișierului de intrare CalculiX.
Example of lines in .inp file:
*DLOAD
Eall,GRAV,9810,0.0,0.0,-1.0
where 9810 is gravity acceleration in [mm/s^2]
*DLOAD
Eall,GRAV,9810,0.0,0.0,-1.0
where 9810 is a gravity acceleration magnitude in [mm/s^2], and 0,0,-1 is the direction vector. The value can be set as a multiple of standard gravity acceleration to simulate loading of e.g. 4g.
