求助大神:用solid90热分析求解，用solid186结构分析求解。进行单元类型转换时出现错误说“solid186没有温度自由度，所以etchg tts命令忽略了solid186”.进行结构分析要啥温度自由度？还有要是我选择的单元本来就有温度与X Y Z自由度就不用进行单元类型转换啊？例如plane13 solid5 发自小木虫Android客户端 |

对流换热系数也要删掉么？我只是删掉了ddele,all,temp没有进行sfdele。电脑只是进行了警告elements of type solid186 do not have a temperature degree of freedom so the etchg tts command ignoees them.还有一个问题就是热分析结束后没有rth文件，我百度大家说用rst 文件也可以，我的rst文件我用list result打开里面是有结果的，但是我在ldread的时候说我的.rst文件 is not available. 谢谢！！！！ 发自小木虫Android客户端 |
