Descriere

Crée une contrainte FEM pour une condition de limite de température.

2D plate subjected to temperature difference

Utilizare

Click pe or choose Model → Thermal Constraints → Constraint temperature din meniul principal.
Selectați în vizualizarea 3D obiectul(e) la care trebuie aplicată constrângerea, care poate fi
1. vertices (corners)
2. edges
3. faces
Introduceți o temperatură pentru a fi aplicată obiectului.

Properties

DateEnable Amplitude - introduced in 1.1: Enables the use of CalculiX's amplitude for the time variation of the temperature boundary condition. At a given time, magnitude of the boundary condition 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

Notă

Constrângerea utilizează *BOUNDARY card in CalculiX. constrângerea de temperatură este explicat la http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node163.html
