在Fluent中材料库选择coal-hv出现下面语句是什么意思？

飞鸟sugar

材料库中的流体中选择coal-hv出现下面语句：
Material coal-hv-volatiles:
  New property "Density" has been added.
  Selecting constant method for "Density" -- data required.
  New property "Thermal Conductivity" has been added.
  Selecting constant method for "Thermal Conductivity" -- data required.
  New property "Viscosity" has been added.
  Selecting constant method for "Viscosity" -- data required.

这段话是什么意思呀？
copy后properties中的密度怎么会是1kg/m3，好奇怪

xrs333

data required，就是需要你给数据。

也就是说properties里面出现的density Viscosity的原有值不对，
要我自己添加  密度，传热系数和黏度吗？
谢谢斑竹大人！！！
