Background cell in MCNP code

[MohammadrezaMC2]

Hello,
Thank you for your wonderful kit, I have a problem: whenever you want to convert the geometry to MCNP code you have to enclose your whole geometry with a bounding box (measures=> Dimensions => bounding box) otherwise an error will appear. But when it is converted a surface named "0" is created in background cells which is not defined and the code will be useless
How can I correct this
Best regards

I would like to confirm which version of MCNP you are using. For normal MCNP CSG (i.e. MCNP5) you don't need to take care of the bounding box. But for the mesh geometry used in MCNP6 you have to do this operation. The surface 0 in the pseudo mesh cell means they are mesh cells without surface information. The embed card will provide the link of this mesh cell to the mesh in the Abaqus file.

Hello Version 5.0.1 was used when this error occured , I have two other question , 1. is it possible for MCCAD to read a MCNP code ? if yes, how should I do it? 2. How should we display the 'test.gdml' in OpenGL ? can you give me more detail? thanks again for your kit
