怎么样才能switch variable density OFF 啊？
我建了一个模型，可是有很多的错误。其中一个关键的是： 算出来负数的密度。ａｎｓｙｓ的提示是，关掉ｄｅｎｓｉｔｙ，但是不知道怎么弄，帮助中也没有看到，不知道大家怎么弄的啊？
Negative density calculated. Solution terminated. This could be causedby a property error or a divergent solution. %/ %C:1 %I:2.
When this message occurs early in the solution, it probably meansthat the properties were specified incorrectly.When it occurs after a fewiterations, it probably means divergence (which could also be due to a badspecification).You can switch variable density OFFto allow any swings in the solution to stabilize, and then restart the analysis.
谢谢了。
