求教《最新经典ANSYS及WORKBENCH教程》中的一个例子

yssure

558页的例子，一个钝头圆柱体，以马赫数0.8飞行10s后的温度及流场分布。在其命令流文件中（光盘中的fl04）将空气的属性设置为
mp,ex,1,1
请教，这是什么意思？

AaronSpark

你是不是命令没写全啊

yssure

请大家看看详细的命令流，上机试一下

没见过，看不懂

lvgang637

定义的材料属性，具体的什么意思，你输入help进行查询一下就可以，我感觉没什么难的，就是代号的含义问题。

lm7a509

学习中！！

别胡说了

应该是密度和弹性模量吧

jxxansys

mp,ex,1,1；
ex应该是弹性模量

361194239

我也觉得是弹性模量！前边那个mp不就是材料特性呢？！

wwb_1982

mp,ex,1,1  就是设置的弹性模量！！！
