Can't simulate airflow around a sketchup model
I have followed this video guide on how to simulate airflow in a sectioned object
But I get stuck at the 3:15 part where it says to interesect both volumes. My problem is that when I import my sketchup model it imports as a face, nothing else. There is no volume, no edges, nothing imported but a face.
Here is an image showing the object that I am trying to evaluate and the problem described:
I can't get past that point and I can't find another way to simulate the airflow around that object. All I want is to see how the air behaves with shapes like that one.
I have also followed the export/import instructions that were provided here http://www.symscape.com/node/1247
Is there any way that I can turn that into a volume or any other way to simulate the airflow around an object like that one, something like the sphynx simulation http://www.symscape.com/blog/great-sphinx-cfd-wind-erosion-study
I have also uploaded the sketchup files of the original model in case it is needed, they have been compressed and can be downloaded here: http://www78.zippyshare.com/v/45361415/file.html
