Optional modeling of coupled heat transfer
When coupled temperature–pore pressure elements are used, heat transfer is modeled in these elements by default. However, you may optionally choose to switch off heat transfer within these elements during some steps in the analysis. This feature may be helpful in reducing computation time during certain phases in the analysis when heat transfer is not an important part of the overall physics of the problem.
Input File Usage: Use the following option either during a transient or a steady-state procedure to suppress heat transfer modeling:
*SOILS, CONSOLIDATION, HEAT=NO
Abaqus/CAE Usage: Switching off the heat transfer part of the physics is not supported in Abaqus/CAE.
展開 Introducing an effective heat transfer area has solved the problems and a unique correlation is proposed.Numerical simulations also clarified the effect of thermal conductivity ratio on the non-dimensional effective heat transfer area, and further the heat transfer characteristics when two or more module packages are set in the same duct.

展開 對于雙向耦合的流體/體溫度計算來說，我們的建議方案是：固體模型傳遞給流體模型表面溫度
●流體模型傳遞給固體模型對流換熱系數和響應的參考溫度
STAR CCM Orline
■單熱模型：不包括相變、輻射換熱
◆使用 Specified Y+ Heat transfer Coefficient和 Specified Y+ Heat transfer Reference Temperature
多熱模型：流體流動+輻射+相變
◆使用 Local heat transfer coefficient和 Local Heat Transfer Reference Temperature
1)局部換熱系數 Local heat transfer coefficient(LHTC)
不合理的參考溫度將會造成不合理的數值對于lowy+網格來說，其結果與文獻差別較大
2)設置y+值換熱系數 Specified y+ Heat transfer coefficient(Sy+HTC)
●合理的y+值可以得到與文件一致的數值不需要選擇參考溫度
3)換熱系數 Heat transfer coefficient(HTC)
危險，如果選擇不合理的參考溫度，可能得到負值的HTC當溫度變化是，比較難以確定參考溫度
4)虛擬局部換熱系數 /irtual local heat transfer coefficient( VLHTC
危險，謹慎使用不與任何參考溫度配對與文獻的數值差別較大

當軟件自動生成邊界條件后，缺少了對稱的邊界條件，這需要創建新的邊界條件，把對應的網格分到相應的分組；在編輯Bearing-Die1等邊界條件時，要注意其網格的接觸類型及熱傳導系數，即是圖5中Contact type和Heat transfer coeff這兩個選項，這個邊界條件的網格接觸類型應為Mismatched，熱傳導系數為3 000 W/m2·℃。
其次是物理場相關：heat transfer(傳熱)、mass transfer(傳質)、natural convection(自然對流)、electric field(電場)、magnetic field(磁場)、dielectrophoresis(介電泳)、stress(應力)等。
其輸出的檔案記錄了初始條件，以便進行高階仿真，如線性靜態特性 (linear static)、挫曲效應 (buckling)、預應力 (pre-stress)、模態動力 (modal dynamics)、非線性 (nonlinear)、穩恒態 (steady state)、及瞬時的熱傳 (transient heat transfer)。
Specifically, the highly porous microstructure with multiscale pores inside the cement aerogel greatly inhibits heat transfer, therefore achieving ultralow thermal conductivity (0.025 W/mK).
