Star-CCM+ and Gridgen
 

I am using Gridgen to generate meshes in .grd format for STAR-CCM+. So far I have been using default value for dimensions. For example, pipe dia=10.

The query is: *What is the default units of demensions i.e. if the input is "dia=10", is it 10 mm/cm/m/inch ?

*Even though BC is set at inlet and outlet in Gridgen, while importing the data in STAR-CCM+, it shows them as wall!!

Thanks a lot,
