电热分析 警告 显示热流几乎为0怎么办

警告显示 There is zero HEAT FLUX everywhere in the model based on the default criterion. please check the value of the average HEAT FLUX during the current iteration to verify that the HEAT FLUX is small enough to be treated as zero. if not, please use the solution controls to reset the criterion for zero HEAT FLUX.  复合材料碳纤维参数   0.0002*0.03*0.016  密度1790  电导率   正交 39/Ωmm，0.025/Ωmm，0.025/Ωmm  比热  712  都是标准单位m   这是哪里出问题了
