Any help would be appreciated- it is urgent<\/p>\n

Basically, I am performing a CFD analysis of a tree with a solid trunk, and a porous crown. I have the inertial resistance coefficient of 200 m^-1, but when I input it, my crown is way too porous (it should be 96% porous). As a result my pressures are not quite correct. I have experimented and used random values, and the pressures now are plausible:<\/p>\n

<\/p>\n

Furthermore, I need to import those pressures and apply it onto one side of the tree in a static structural analysis, however, (I think?) my stresses outputted are a bit too low:<\/p>\n

<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 I think it may be to do with my named selections for which I apply the pressure loads to (I have selected all the faces of the tree):<\/p>\n

<\/p>\n

 <\/p>\n

 <\/p>\n

Many Thanks,<\/p>\n
