Descriere

Această constrângere specifică schimbul de căldură (transferul de căldură al filmului) al unei suprafețe la temperatura T și cu un coeficient de schimb termic h și o temperatură ambiantă T₀ . Fluxul de căldură convectiv q poate satisface: q = h(T -T₀)

Utilizare

1. Click pe sau selctați Model → Thermal Constraints → Constraint heatflux din meniul principal.
2. Selectați în vizualizarea 3D suprafața/elepe care constrângerea trebuie aplicată.
3. Introduceți temperatura dorită a suprafeței, coeficientul filmului și temperatura ambiantă.

Notă

1. Constrângerea utilizează *FILM card in CalculiX. constrângerea fluxului de căldură este explicat la http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node203.html
