I'm having problems importing a freeform model into CFX. The model is a nurbs based geometry modelled in Rhino. The model is checked for watertightness in rhino. The model is completely closed in rhino and encloses a closed volume. I exported it as IGES to CFX. When I open CFX-pre im getting this message:

CFX-Pre Application Error

ERROR
There was a problem importing the mesh from the requested file.
The importing process reported the following problem:

Model "Model" does not have a valid mesh associated with it.

Body B2997 is an unsuppressed surface body that does not enclose
a volume. Only 3D volume meshes can be imported. If your model
contains valid bodies as well as surface bodies then suppress
the surface bodies and remesh before continuing.

ERROR: Failed to export model.


So the geometry isnt a closed volume anymore. This happened somewhere when importing into CFX or exporting from rhino. Does anyone know how to fix it?
