如題,使用ansys workbench 22R1-23R1版本的耦合穩態進行分析熱應力,先進行穩態熱-穩態力順序耦合分析沒出現問題,使用穩態耦合分析出現:The calculated specific heat at constant strain (Cv) is negative. (See section "Thermoelasticity" of the Theory Reference for the definition of Cv.) Please verify the input of thermal material quantities for consistency. 反復檢查工程數據找不到恒定熱容的輸入選項如圖1,打開workbench材料部分里的參數由恒定熱容數字均為真如圖2,圖3是仿真流,目前一直找不到解決的辦法
