Research on converting CAD model to MCNP model based on STEP file
MCNP input file has the characteristics of complicated form and is error-prone in describing geometry model. Therefore we need design and implement an algorithm of conversion general CAD model to MCNP model to solve the existing problems in MCNP aided modeling software. And it can convert the CAD model to MCNP input file. In order to achieve the above goal, this paper concentrates on converting CAD model to MCNP model, after analyzing STEP neutral File and MCNP INP file, we designed an algorithm to achieve converting STEP file to INP file. The result of experiment shows that it has better applicability than the other converting algorithm after getting geometry information of the STEP file. And this algorithm can be widely used and make the communication between CAD systems and MCNP models.
