每日一问！（4）
老大帮我看看，这个热成形设置好了以后要运行的时候出现的问题，图在下面 *** ERROR *** ISOTHERMAL CALCULATION:IMPOSSIBLE TO IMPOSE TEMPERATURE
运算以后出现这个，是不是温度没有导进来，怎么样才能导进来温度呢 gravity下设置了温度了吗? 设置了，凸模120 凹模120 压边圈25 板料860 这个多工序？ 忘了设PICKING属性了？？ 把重力过程下的温度去掉,软件中重力过程是不考虑温度的 谢谢斑竹！ 还是有问题，如果不设置温度，就说 重力过程必须设置温度，我采用picking的方式以后还是说Gravity will be isothermal 运算出现下面这些，老大帮帮忙。
