Dear colleagues,
I'm an italian student of the departement of Building Engineering and in this period I'm working on a project about natural ventilation of buildings. In particulary I would like to compare the resuslts of a study that I made in a wind tunnel with the results of Comsol.
In this days I tried to import a 3D model in comsol: it's a model made with Rhynoceros so I save it in the ACIS format in order to import it with comsol, but when I import it I'm not capable to import it correctly and I read the follow message: "error 2152 Unable to determine topology of point in 2D". I tried to import every single different part of the model and it was good, but when I'm going to import the entire model i found the error 2152.
It dipens probabily by the big number of elements? I really don't know..but it's not a very big model, It has been designed in metres and there are not complex geometries. Every part of the model is made by solid elements and not surface.
Thank you for your consideration.
My best regards.
Alessandro Blanc

this is the model made with Rhynoceros.
